The EWC Spatial Data Index is a simple web tool you can use to search by country for free and low-cost, in-house and external spatial datasets for the Asia Pacific region. Spatial data can be used to create study area maps, conduct spatial analyses in research, or as training data for seminars and workshops that incorporate GIS and mapping. Spatial Information Services collects and processes a wide variety of digital, spatial datasets including satellite imagery, aerial photographs, and other thematic GIS layers (e.g., roads, rivers, village and city points, administrative boundaries, land use/land cover, elevation, etc.). This is an experimental, evolving tool. Contact John Vogler for more information about this tool and/or available datasets.

Additional EWC Spatial Data Index Links and Information:
More Global Datasets in Spatial Information Service's library:
Types of Spatial Data: Raster and Vector Format:
Satellite Imagery (Raster format)
Aerial Photography (Hardcopy and digital raster formats)
Digital Elevation (Raster format)
Digital Vector Data (e.g., point, line and area representations of real-world phenomena such as cities, roads and country boundaries)
GPS Data (the Global Positioning Systems)
Others include: 1) Demographic Data with links to spatial units such as blocks, blockgroups, tracts, communes, counties, etc. 2) Cadastre Data 3) Address Databases can be Geocoded to produce point maps of address locations. |
The Added Value of Adding Maps 1) Just about everything that happens or exists, does so somewhere. 2) A vast majority of data has a geographic component (the Where?). 3) Maps provide visual, geographic context to papers, publications and presentations. 4) Maps can communicate large amounts of information in a simple, effective manner. 5) Maps may reveal geographic patterns and relationships in your data that are not apparent in the raw tabular data. FOR EXAMPLE: Click on map of Cancer Mortality Rates by US County for full resolution map. Source: US Census.
6) Maps are relatively easy to produce. How?
