Why TerraGo

Challenges

  • Geospatial digital files (Satellite Image, Terrain Data, Vector data) are too large to pass around to the end users.

  • Valuable geospatial information are locked inside complex GIS applications and only a small number of professionals can possibly understand how to use them effectively.

  • Special application software /viewers are usually needed to interact with geospatial data

  • Info-rich output files carrying valuable GIS information are eventually flattened and become less interactive as they finally reach the destination.

  • Transfer of geospatial information to less skilled end users is difficult.

  • Time, training and resources are required to translate information into actionable information.

  • Geospatial data are needed to combine in a standalone file along with text reports, field photographs and other multimedia files.

  • A “round trip” mapping platform is required to publish maps or reports that would provide a platform to transfer data from a complex GIS system to end users and from end users back to the GIS system at the Organization Headquarters.

  • The interactive GIS maps and imagery are required for every officers in the field that could also be used in off-line mode when all the network connections would be shut down during disasters or no network connection would be available because of remote distances.

Solutions/Key Benefits

  • Provides a standard format for use and exchange of GIS documents with non-GIS users and allows them to leverage valuable geospatial assets.

  • Allows organizations to consume and optimize data from any source and create a geo-enabled PDF for rapid, mass distribution of digital geospatial assets.

  • Provides free Toolbar for Adobe Reader plug-in to view GeoPDF.

  • Contains significantly smaller data files in contrast to traditional files in GIS formats.

  • Complies with Adobe’s PDF specification.

  • Is identified as “Best Practice” by Open Geospatial Consortium (OGC).

  • TerraGo’s GeoPDF is especially powerful in its application primarily due to the following functionalities:

Easy-to-use

GeoPDF can be used without GIS applications and special skills for GIS. One can see PDF-type digital map with geospatial data on Adobe Reader/Acrobat with a free toolbar for GeoPDF. After import GeoPDF map into Adobe reader user can use the map in a variety of ways

• Find map coordinates (X, Y and Z)

• Find a particular location on a map

• Customize view by turning layers on and off

• Switch to Google Maps™ Bing MapsTM view

• Measure distance, area and bearing on a map

• Track location via GPS

• View associated attribute data, meta data

• Search levels and features

Easy-to-go

GeoPDF is suitable for use outside the office since the data size is very small compared to the original satellite imagery and geospatial datasets. Below is an example of a vastly reduced file size (5.0 MB) in a GeoPDF format in contrast to other GIS file formats

Topographic Map 1:50,000 Scale –300 dpi

312.0 MB GeoTIFF

10.0 MB SHP

9.7 MB JPEG

8.8 MB TIFF/ZIP

5.0 MB GeoPDF

Easy-to-share updated information

Point, line, polyline, polygon, notes and comments can be added as GeoMarks on GeoPDF. All GeoMarks have geospatial information and can be exported to KML/SHP files. This feature enables to import other GeoPDF files or GIS applications and share updated information among lots of other users
