Intergeo 2011 exhibition in Nürnberg (Germany) has been the third international presentation of DigiTerra, this year jointly with Ortograph, a Hungarian developer of building surveying software. We have demonstrated the latest improvements in DigiTerra Explorer, like the offline background map feature or the botanical analysis module. As most important result of this trade show, we have concluded new agreements with producers of GPS-receiver units, such as Juniper Systems or Geneq Inc. for the distribution of DigiTerra Explorer through their dealer network. Existing and new customers visited the booth of DigiTerra, additional resellers joined to our network. Existing distributor partners shared their success stories that could not have been possible without DigiTerra Explorer. Have a look for example at the Paleontological research project in Portugal.

With the new Background Map tool of DigiTerra Explorer it is possible prepare individual base maps from online sources and use them during data collection. This can be done without Internet connection in the field!

Navigation with free high-resolution aerial imagery and maps

During field data collection, a satellite image, an aerial photograph or even a topographic map improves significantly the quality of mobile mapping. All these data are accessible but often with difficulties and high costs. However, when using smart phones during online navigation or browsing websites, several free aerial maps are available from online sources. The question arises: if the online version is free, why can't we take them with us to the field? The data would still be free, but we should use a mobile phone with GPS in one hand for displaying maps, and a PDA for data capturing in the other hand. Surely, this would be expensive and extremely inconvenient.
