Compares ArcGIS against GRASS, QGIS, uDig, gvSIG,OpenJUMP, and MapWindow for the Library domain.
 +
 +
: "Each of the individual FOSS GIS packages had their own particular strengths and weaknesses and some performed well for thematic mapping. The FOSS packages generally were weaker compared to ArcGIS in terms of support for various projection and coordinate systems, joining attribute data to GIS files, and automatic labeling, but their advantage is that they were free in terms of cost and licensing restrictions. When coupled with plug-ins and helper applications the viability of the FOSS GIS packages increased."

'''18 April 2008: [http://lists.burri.to/pipermail/geowanking/2008-April/thread.html Geowanking: ArcView 3.1 replacement]'''
 +
 +
"[Oxford Archaeology] are looking at gvsig and qgis as the main options [for ArcGIS], gvsig because it can use cad data, and qgis because we like the grass integration and it's slightly more user-friendly for english speakers (the translated version of gvsig still has some spanish bits in it). With slight changes to our work-flows, we are finding that these two packages will do almost everything we need a gis to do, with the exception of producing high-quality illustrations. To achieve this we are currently looking at export to svg or postscript for final editing in inkscape, but that's a work in progress."

 +
'''24 April 2008: [http://lists.osgeo.org/pipermail/discuss/2008-April/thread.html OSGeo-Discuss: Can I do the same GIS tasks with OS (as with ESRI)?]'''
 +
 +
This email thread provides numerous opinions for and against using Open Source Geospatial Software.
 +
 +
[http://lists.osgeo.org/pipermail/discuss/2008-April/003458.html Paul Ramsey notes there is not a direct Open Source replacement for Arc View]:
 +
 +
''I think it's contingent on us as evangelizers to not over-sell. I
 +
would not recommend QGIS or any other open source desktop to someone
 +
whose prior experience was Arc* until I had a clear understanding of
 +
the use case. In response to the query "can I replace ArcView with
 +
open source", my answer is "in general, no, but maybe for a specific
 +
use case".''
 +
 +
[http://lists.osgeo.org/pipermail/discuss/2008-April/003453.html John Callahan provides a good summary]:
 +
 +
''I've been an ESRI user (AV 3.x, ArcGIS 8/9, ArcIMS, ArcGIS Server, ArcSDE) for 12+ years and have recently started exploring FOSS software.  And I haven't disagreed with any of the responses so far.  You will definitely need multiple programs to do what a single ESRI program can do.  IMO, this is a good thing.  One of the main reasons for my migration is I'm tired of running large, complicated, expensive software and all the extra baggage that comes with it to use only 10% of what the software can do. (see ArcGIS Server.)''
 +
 +
''You can do all the analysis and more of ArcGIS Desktop and extensions using GRASS, QGIS, SAGA, GeoTools, GDAL/OGR, PROJ4, or R Statistics along with a programming language like Python, Java or others.  (IMO, this is a better solution than ESRI.)    You can do just about anything you want on the web server end with MapServer, GeoServer, FeatureServer (and maybe TileCache or GeoNetwork for metadata) with any of a dozen or more clients (OpenLayers, ka-Map, MapGuide etc...).  And you can do a lot of database work with Postgres/PostGIS, a much simpler, less costly solution than ArcSDE+RDBMS.  And I wouldn't count out the role of free, non-open source packages like Google products and Oracle Express (11g should have Spatial included.)''
 +
 +
''From my experience (limited in the FOSS world), I have found three basic hurdles:
 +
# ''Cartography.  Whether on the screen, PDF outputs, or print publications, ArcMap is easy and looks great. (Although R Statistics produces better looking charts and graphs than ArcGIS.)''
 +
# ''Versioned editing.  This is important for groups with multiple concurrent editors or that has a particular hierarchical workflow with their GIS data.''
 +
# ''Storage and serving of very large (50+ GB) raster datasets.  PostGIS does not support rasters yet; Oracle Spatial does though.  I'm still not sure if storing rasters in a database is a good idea but ArcSDE sure makes it easy, and with good performance when used in conjunction with other ESRI products.''

 +
 +
Todd Buchanan's master thesis compared ArcGIS 9.0 and GRASS 6.0 for a use case: "Characterization of Urban Sprawl for Eugene-Springfield, Oregon". He took detailed notes using both and found "ArcGIS is more straightforward than GRASS. However, GRASS proved itself fully capable of performing the operations required by the case study and outperformed ArcGIS in several categories."

 +
Note: GRASS GIS is even better now and has been integrated with the user friendly QGIS and Sextante since this study.

"... Postgres performs better than Oracle 11g both in the Cold Phase and Warm Phase. Though in few queries Oracle 11g performed better but on the whole Postgres overpowered Oracle 11g. In the warm phase in 3 out of 4 queries Postgres performed significantly well, from this we can conclude that Postgres has better automatic memory management capabilities and page replacement policies... On the whole it is the open-source that wins the game!"

===PostGIS versus MySQL Spatial===
 +
June 2009
 +
 +
In speed, PostGIS wins but not by orders of magnitude. The amount of functionality in MySQL Spatial remains very very small. You can do simple store-and-retrieve operations. Many of the spatial operations that are standard in full spatial databases don’t exist or are (confusingly, as some users have commented) stubbed out against bounding box tests instead.

The EU Digital Agenda for Europe initiative supports the SEIS principle aiming to generate information sharing through common, free, open source software. For example, an EU legal framework for licensing open source software now exists (ISA EUPL) and governments are increasingly keen to develop its use. Actions under the EU Digital Agenda are creating a safer and better-performing digital environment, improving access conditions and interoperability and stimulating the growth of cross-border e-Government services. The open source and open data movement offers significant opportunities for further developing the SEIS but

more open-source empowered applications ensuring compatibility across Member States will be needed for managing and sharing environmental information

Open Data
 +
 
 +
1. Ministries must take steps to expand public access to government data by making it available online unless restricted by law, contract or policy.
 +
 
 +
2. Ministries must re-prioritize and expand data collection efforts towards those that enable citizens and sectors to create value from government data.
 +
 
 +
3. Ministries must adopt B.C.'s open license for data and ensure data accessibility through DataBC in accordance with B.C.'s Open Data Policy, which includes the requirement that data be published in an open machine-readable format.
 +
 
 +
4. DataBC must ensure that citizens can give feedback on and assessment of the quality of published information and provide input to which data should be prioritized for publication.
 +
 
 +
Open Information
 +
 
 +
1. To the extent practicable and subject to the Freedom of Information and Protection of Privacy Act (FOIPPA) and other valid restrictions, ministries should use modern technology to disseminate useful information in a routine way rather than waiting for specific requests under FOIPPA.

*'''Choose FOSS''': The South African government will implement FOSS unless proprietary software proves to be significantly superior. Whenever the advantages of FOSS and proprietary software are comparable FOSS will be implemented when choosing a software solution for a new project. Whenever FOSS is not implemented, then reasons must be provided to justify implementing proprietary software.
 +
*'''Use FOSS/Open Content Licensing''': The South African government will ensure all government content and content developed using government resources is made Open Content, unless analysis on specific content shows that proprietary licensing or confidentiality is substantially beneficial.
 +
*'''Develop in FOSS''': All new software developed for or by the South African government will be based on open standards, adherent to FOSS principles, and be licensed using a FOSS license where possible.
 +
*'''Migrate to FOSS''': The South African government will migrate current proprietary software to FOSS whenever comparable software exists.
 +
*'''Promote FOSS in South Africa''': The South African government will encourage the use of Open Content and Open Standards within South Africa. They will encourage the use of Open Content and Open Standards.

Review of Open Source Desktop Clients

Compare ArcGIS against Open Source GIS Desktop

September 2009 http://gothos.info/resource_files/fpd_libhitech_foss_gis_march2010.pdf

Compares ArcGIS against GRASS, QGIS, uDig, gvSIG,OpenJUMP, and MapWindow for the Library domain.

"Each of the individual FOSS GIS packages had their own particular strengths and weaknesses and some performed well for thematic mapping. The FOSS packages generally were weaker compared to ArcGIS in terms of support for various projection and coordinate systems, joining attribute data to GIS files, and automatic labeling, but their advantage is that they were free in terms of cost and licensing restrictions. When coupled with plug-ins and helper applications the viability of the FOSS GIS packages increased."

Email threads discussing merits and disadvantages of OSGeo Desktop

18 April 2008: Geowanking: ArcView 3.1 replacement

"[Oxford Archaeology] are looking at gvsig and qgis as the main options [for ArcGIS], gvsig because it can use cad data, and qgis because we like the grass integration and it's slightly more user-friendly for english speakers (the translated version of gvsig still has some spanish bits in it). With slight changes to our work-flows, we are finding that these two packages will do almost everything we need a gis to do, with the exception of producing high-quality illustrations. To achieve this we are currently looking at export to svg or postscript for final editing in inkscape, but that's a work in progress."

24 April 2008: OSGeo-Discuss: Can I do the same GIS tasks with OS (as with ESRI)?

This email thread provides numerous opinions for and against using Open Source Geospatial Software.

Paul Ramsey notes there is not a direct Open Source replacement for Arc View:

I think it's contingent on us as evangelizers to not over-sell. I would not recommend QGIS or any other open source desktop to someone whose prior experience was Arc* until I had a clear understanding of the use case. In response to the query "can I replace ArcView with open source", my answer is "in general, no, but maybe for a specific use case".

John Callahan provides a good summary:

I've been an ESRI user (AV 3.x, ArcGIS 8/9, ArcIMS, ArcGIS Server, ArcSDE) for 12+ years and have recently started exploring FOSS software. And I haven't disagreed with any of the responses so far. You will definitely need multiple programs to do what a single ESRI program can do. IMO, this is a good thing. One of the main reasons for my migration is I'm tired of running large, complicated, expensive software and all the extra baggage that comes with it to use only 10% of what the software can do. (see ArcGIS Server.)

You can do all the analysis and more of ArcGIS Desktop and extensions using GRASS, QGIS, SAGA, GeoTools, GDAL/OGR, PROJ4, or R Statistics along with a programming language like Python, Java or others. (IMO, this is a better solution than ESRI.) You can do just about anything you want on the web server end with MapServer, GeoServer, FeatureServer (and maybe TileCache or GeoNetwork for metadata) with any of a dozen or more clients (OpenLayers, ka-Map, MapGuide etc...). And you can do a lot of database work with Postgres/PostGIS, a much simpler, less costly solution than ArcSDE+RDBMS. And I wouldn't count out the role of free, non-open source packages like Google products and Oracle Express (11g should have Spatial included.)

From my experience (limited in the FOSS world), I have found three basic hurdles:

  1. Cartography. Whether on the screen, PDF outputs, or print publications, ArcMap is easy and looks great. (Although R Statistics produces better looking charts and graphs than ArcGIS.)
  2. Versioned editing. This is important for groups with multiple concurrent editors or that has a particular hierarchical workflow with their GIS data.
  3. Storage and serving of very large (50+ GB) raster datasets. PostGIS does not support rasters yet; Oracle Spatial does though. I'm still not sure if storing rasters in a database is a good idea but ArcSDE sure makes it easy, and with good performance when used in conjunction with other ESRI products.

Current work addressing Open Source holes include:

GRASS

GRASS64 with ArcGIS93 in education at North Carolina State University

ARCGIS 9.0 vs GRASS 6.0

August 2005, Comparison of ARCGIS 9.0 and GRASS 6.0

Todd Buchanan's master thesis compared ArcGIS 9.0 and GRASS 6.0 for a use case: "Characterization of Urban Sprawl for Eugene-Springfield, Oregon". He took detailed notes using both and found "ArcGIS is more straightforward than GRASS. However, GRASS proved itself fully capable of performing the operations required by the case study and outperformed ArcGIS in several categories."

Note: GRASS GIS is even better now and has been integrated with the user friendly QGIS and Sextante since this study.

PostGIS vs Oracle Spatial benchmarking

February 2012

"... Postgres performs better than Oracle 11g both in the Cold Phase and Warm Phase. Though in few queries Oracle 11g performed better but on the whole Postgres overpowered Oracle 11g. In the warm phase in 3 out of 4 queries Postgres performed significantly well, from this we can conclude that Postgres has better automatic memory management capabilities and page replacement policies... On the whole it is the open-source that wins the game!"

PostGIS versus MySQL Spatial

June 2009

In speed, PostGIS wins but not by orders of magnitude. The amount of functionality in MySQL Spatial remains very very small. You can do simple store-and-retrieve operations. Many of the spatial operations that are standard in full spatial databases don’t exist or are (confusingly, as some users have commented) stubbed out against bounding box tests instead. http://docs.opengeo.org/geospiel/2009/06/16/postgis-versus-mysql-spatial/

European Union

February 2008, Commission Communication towards a Shared Environmental Information System (SEIS)

This Communication sets out an approach to modernise and simplify the collection, exchange and use of the data and information required for environemntal monitoring and reporting in Europe. Id defines a set of principles on the basis of which the collection, exchange and use of environmental data and information should be organised in the future. FOSS adressed directly as one of the principles information sharing and processing should be supported through common, free open-source software tools.

June 2010, EU Guidelines for Public Administrations purchasing software

This guide describes in business terms, the importance of using Open Standards in order to adhere to EU purchasing criteria of fair competition, transparency, and long term value for money.

January 2013, Staff Working Document "EU Shared Environmental Information System – Implementation Outlook"

The EU Digital Agenda for Europe initiative supports the SEIS principle aiming to generate information sharing through common, free, open source software. For example, an EU legal framework for licensing open source software now exists (ISA EUPL) and governments are increasingly keen to develop its use. Actions under the EU Digital Agenda are creating a safer and better-performing digital environment, improving access conditions and interoperability and stimulating the growth of cross-border e-Government services. The open source and open data movement offers significant opportunities for further developing the SEIS but more open-source empowered applications ensuring compatibility across Member States will be needed for managing and sharing environmental information

Why write a Case Study?

A case study discusses how a specific situation was identified, which solutions were investigated and selected, and a summary of the results.

Solution architects use relevant case studies to support a solution they are building.

Writing a case study about your project gives others the confidence to follow in your footsteps which in turn increases investment in your tools of choice. Publishing your experience gives positive feedback to those involved in your project, reinforcing your success, encouraging colleagues to take on additional challenges, allowing the project to continue to grow.

We would like to see case studies which cover a range of use cases, especially from organizations with a low risk tolerance. Many organizations approach Open Source in little steps gradually integrating it with existing infrastructure and find targeted small case studies valuable.

What to write?

One to three pages is good, with a graphic per page.

The case study should cover:

  • Date
  • Problem
  • Evaluations
  • Implementation, including integration with other infrastructure
  • Problems faced and how they were overcome
  • Return on Investment
  • Future plans
  • Who else might benefit from your experience

How to publish?

Consider submitting an article to the OSGeo Journal. Here are the basic guidelines for authors.
