SPOT THEMA

Land use in cities
-

SPOT Thema is an urban land use management database product covering mainland France. It is a vector database generated from SPOT imagery, compatible with a broad spectrum of standard land planning and management applications. Currently based on SPOT 1 to 4 data, a SPOT Thema database can also be compiled with SPOT 5 imagery on request.

 
Features
-

 

SPOT Thema contains two levels of information:
  • the first level integrates 8 themes to give you a general picture (for use at a scale of 1:50 000)
  • the more detailed second level integrates 29 themes for applications requiring finer detail of land use/land cover (for use at a scale of 1:25 000).
The first level groups and synthesizes these more detailed data.
SPOT Thema also includes a raster layer containing data on construction features that can be overlaid directly on vector data to provide even richer content.
 
- SPOT Thema lets you keep track of changing land use in your region through three tailored products:
  • A baseline product generated from recent SPOT imagery, providing a database of current land use information.
  • An evolution product generated from SPOT imagery acquired at an earlier date, allowing retrospective analysis as far back as 1986. This product comes with an analysis product generated by merging the baseline product and the evolution product.
  • An update product generated from SPOT imagery to be acquired at a later date, making it possible to observe land use change at a given moment, thanks to the SPOT satellites’ frequent revisit capability. This product comes with the analysis product generated by cross-correlating the baseline product and the evolution product.
