Abstract

Conference
FOSS4G 2010
Title
A comparison of Mobile GIS applications
Authors
Abstract
Free and open source software for GIS has evolved a lot from last years, faster than privative alternatives and now every FOSS4G expert has several very good tools to use on desktop PCs and web.
The mobile field is a bit different and few experts are using free and open source mobile GIS, despite of good applications exist. Last years with the appearance of Android OS phones a new wave of map applications have been developed.
At this talk, different mobile GIS applications will be analyzed, compared and tabulated.
The objectives are:
  • To provide a detailed list of FOSS mobile GIS applications
  • Find how far are free and open source software from privative alternatives
  • Help to choose the best tool for every project
The main aspects of the comparison will be: functionality, complexity, customizability, formats compatibility and performance and the applications compared will be: ArcPad, gvSIG Mobile, BeeGIS, TangoGPS, Google Maps Mobile, gvSIG Mini, Layar and others

Product List

gvSIG Mobile

gvSIG Mobile is a project aimed to develop a free and open source GIS/SDI client on mobile devices.

gvSIG Mobile is a version of gvSIG Desktop an OSGeo project under incubation, adapted for mobile devices, with support for shapefiles, GPX, KML, GML, ECW, WMS and images, capable of using GPS. Among its features there are tools for project management, display of local and remote information (via WMS standard), layers management (symbols), querying alphanumeric information of the elements, editing data using customized forms, creating GPS tracklogs/waypoints and so on.

Perfomance Comparison

Datasets used

For testing the perfomance of the applications, OSGeo available datasets for FOSS4G 2010 have been used. Shapefiles fo several sizes have been loaded on a PDA for vectorial comparison.

For raster comparison, an official ortophotograph coming from the Spanish National Mapping Agency (CNIG - Centro Nacional de Información Geográfica) of Barcelona area have been downloading in ECW. This image has also been clipped to two image sizes, for testing two different image sizes. GDAL utilities have been used for clipping and resampling.

The layers used for the speed perfomance test have been these ones:

Designed Tests

Methodology

The heterogeneity of platforms and products makes it difficult to desing a common test for all the products. A common test have been designed for Windows Mobile platform, the most powerful in terms of GIS features so far.

The formats supported by the different products are not homogeneous. For instance, only gvSIG Mobile can load vetorial formats other than SHP (GML, KML, ...). On the other hand, gvSIG Mobile only supports ECW as wavelet raster formats, and not MrSID or JPEG 2000. So only common tests have been made in order to get the differences.

Access to remote services hasn't been compared, as ArcPad only accesses ArcIMS/ArcGIS servers, and not standardized ones (WMS, WFS, ...).

Note: As of today, we haven't been able to load a ECW in ArcPad, although it supports this format. (Maybe ArcPad doesn't like GDAL ECW clipping or resampling results).

Speed tests have been made in the same PDA. All of them have been made with no other application running on the PDA. Datasets have been read from the storage card.

Time measurement

The binaries have been used in a PDA to measure the results. The times have been taken manually with a stopwatch. In order to minimize the human error, all the measurements have been taken at least 3 times, and an average have been made. 0,2 seconds have been substracted to all measured times, for removing human response time effects.

Some of the measurements are too fast to be measured by a manual action with a stopwatch. So all measures under 0,2 seconds have been homogenized to 0,2 seconds, with the understanding that it's fast enough to not perceive a delay from the point of view of the user.

Speed test cases

For the three Windows Mobile GIS products (gvSIG Mobile, enebro and ArcPad), the following test have been performed:

  • Vectorial support:
    • Adding a new SHP layer.
    • Zooming by rectangle to a small area.
    • Panning when in the small area.
    • Fit all (zoom to extent).
  • Raster support:
    • Adding a new raster layer.
    • Zooming by rectangle to a small area.
    • Panning when in the small area.
    • Fit all (zoom to extent).

These tests have been executed for every layer.

Device details

The device used for testing has been this one:

  • Model: Acer S200.
  • Processor: Qualcomm QSD8250, running at 1 GHz.
  • SDRAM: 256 MB.
  • ROM: 512 KB.
  • Screen: 480x800 pixels.
