Approach for writing this book
We will start writing this book by listing practical problems and then identifying tools for solving those problems. As the list of problems increases they should be organized into groups etc.
We'd like to develop this page somehow coordinated with the Programming_Languages_Project
- Problem: Share GPS data between applications
- Subproblem: Parse GPX
- Explanation: GPX is an XML application for GPS data. Parsing gives us the GPS data.
- Problem:
- Subproblem: GeoTag Media
- Explanation:
- Problem:
- Subproblem: Track logs
- Explanation:
| Use case | Description | Perl | Ruby | Python |
| Parse GPX | What is GPX? | Perl based solution | Ruby based solution | PyGPX |
| GeoTag Media | RDFWeb geoloc_media.pl (original geoloc_media) | Ruby? | Python? | |
| Track logs | Geo::Track::Log | Ruby | Python |
Editing geospatial data
- Problem: Editing shapefile
- Subproblem: Add or delete a feature
- A solution:
- Subproblem: Change the location of the vertices
- A solution:
- Subproblem: Edit attribute data
- A solution:
- Subproblem: Alter the schema (add or delete fields)
- A solution:
Geocomputation
- Problem: Compute the total area of polygons in a dataset
