Data formats
Eventually we plan to make each type of data available in multiple formats; however, it will take some time to get there. Formats such as SHP, DWG, KML and others, where appropriate, will be provided. Not all data will be available in all formats and other formats may be added to this list.
- CSV/XLS: This is a basic text format that can be opened by many applications including Excel and other spreadsheet applications. Read about CSV format on WikiPedia
Read about XLS on WikiPedia - DWG: DWG is a "de facto GIS standard" format native to Autodesk design and GIS software. It can be consumed by a wide variety of Autodesk and non-Autodesk software packages. Read about DWG format on WikiPedia
- ECW: ECW is a format used for geo-referenced raster images that is highly compressed. Read about ECW on WikiPedia Read about image formats on WikiPedia
- KML: KML is a mark-up language developed by Keyhole Inc. and subsequently acquired by Google to display data in Google Maps, Google Earth and similar applications. KML is an Open Geospatial Consortium standard. Read about KML format on WikiPedia
- MrSID: MrSID (pronounced "Mister SID") is a format used for geo-referenced raster images that is highly compressed. The MrSID version of the facetized orthophotos are only about 5% of the size of their GeoTiff versions. Read about MrSID format on WikiPedia Read about image formats on WikiPedia
- SHP: SHP (pronounced "shape") is a "de facto GIS standard" format native to ESRI GIS software. It can be consumed by a wide variety of ESRI and non-ESRI software packages. Read about SHP format on WikiPedia
- Web feed: A web feed (or news feed) is a data format used for providing users with frequently updated content. Content distributors syndicate a web feed, thereby allowing users to subscribe to it. Read about Web feed on Wikipedia
DWG, SHP, TIF, Mr. SID and ECW formats are projected in UTM zone10, NAD83 (CSRS).
KML and CSV/XLS formats are projected in latitude, longitude (WGS84); this is relavent for CSV/XLS files only if they contain latitude and longitude.
