Erdas Titan 3d Virtual Globe, FlowMap, Gen2shp, Geocoding, Generic Mapping Tools ...

Free & Open Source GIS Software Downloads Part 4

edbs2wkt - Converting the GIS-Format EDBS to Spatial-Database, PostGIS and other using the Well Known Text-Interface. EDBS is a German Fileformat from ALK (Automatisierte Liegenschaftskarte).


Erdas Titan 3D Visualization Client - In ERDAS TITAN Client 2010, users may connect to ERDAS APOLLO catalogs via the TITAN Viewer to execute geoprocesses and visualize results in a 3D virtual globe. Descriptive metadata search results from ERDAS APOLLO catalogs are now also available in an easy-to-read display pane. Search and discovery of data in an APOLLO catalog is much faster, due to integration of REST/JSON API. Performance in the ERDAS TITAN Client Viewer has also been greatly optimized by new algorithms, providing seamless zoom in/out of raster overlays, more memory efficiency (2-3x), multiple times faster loading KML and shapefiles, improvements to loading terrain and basemaps, and navigation enhancements.


Flowmap is a software package dedicated to analyzing and displaying interaction or flow data. This type of data is special in the sense that there are two different
geographic locations connected to each data item: An origin location where the flow starts and an destination location where the flow ends. The flow data itself can be people (e.g. commuters, shoppers, hospital visitors), goods, usage of agricultural services or telecommunication and so on.


gen2shp is a simple C-Progam which can read the format required by the ESRI ArcInfo generate command.


Gen2shp - Implemented in Avenue, can be directly incorporated into AV projects. Converts 2D or 3D ASCII data from one or more generate format text files to one or more (multi-part) shapefiles. Available as Extension or just Scripts.


Generic Mapping Tools (GMT) is a collection of about 60 UNIX tools that allow users to manipulate (x,y) and (x,y,z) data sets (including filtering, trend fitting, gridding, projecting, etc.) and produce Encapsulated PostScript File (EPS) illustrations ranging from simple x-y plots through contour maps to artificially illuminated surfaces and 3-D perspective views in black and white, gray tone, hachure patterns, and 24-bit color. GMT supports 30 common map projections plus linear, log and power scaling, and comes with support data such as coastlines, rivers, and political boundaries.


Geocoding - Map Channels offers free single address and batch geocoding.


More to come! Enjoy.
