During my recent lunch breaks I started working on some OSMHQ mapping near my office. When I got the data downloaded and started to work with it I realized a couple of things:
[1] I need to write some simple tools to help process the data. [2] I really need to define a GIS data model for OSM that will help guide my work. The first tool I'd like to write will take waypoints collected with a recreation grade GIS receiver and exported in GPX format from EasyGPS or another program into a GML 2.0 file that can be imported into OpenJUMP or other GIS programs that support GML 2.0. The GML file will convert each waypoint into a waypoint observation feature with the following feature attributes: - Time of Observation - Estimate Horizontal Accuracy - Primary Observed Feature Type (The primary feature the waypoint "belongs" to.) - Primary Observed Feature Type Name - Waypoint to Feature Geometry Relationship (Describes the relationship of the location of the waypoint observation to the actual geometry representing the feature.) - Mapper Call Sign/Name - Mapper Organization Name This tool will support a step in the OSMHQ mapping process that preserves the raw measurement data that OSM feature geometry is created from. As part of my work on the GIS Data Model for OSMHQ I've come up with a standard set of tags for all OSMHQ features. My second tool will add these tags with default values to each feature contained in a OSM XML file. The user of the tool will be able to set the default values for each of the standard tags prior to the conversion. I'm also thinking about adding GPX and OSM XML import/export support to OpenJUMP. Please let me know if you have any thoughts. The Sunburned Surveyor _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
