1. How can I georeference maps in Cartographica?
   I do not understand something about importing a map. If I have a jpeg map file I can import the image, but the image will not be rectified. How do I geo-reference the map image so imported GPS positions will be properly placed on the image? Versions of Cartographica through 1.1 require the use o ...
2. My shape file doesn't load with the right character set, what can I do?
   The problem Cartographica has extensive support for unicode and importing and exporting of files in other character formats. However, the one problem that it can't solve is figuring out what character set the data is encoded in. For some file formats, there are markers that indicate the characte ...
3. ArcView shape (.shp) files load but don't have any data associated with them
   When using Import Vector to load ESRI Shape File (.shp) data into Cartographica, the resulting feature shape data shows up, but I don't get any of the numeric and textual data that go with it. The ESRI Shape File format is a multi-file format. When obtaining files from other software, it's impor ...
4. How do I import data from a text file?
   Cartographica supports importing data from a text file that is written in standard "CSV" format (Comma-Separated Values). Beyond the normal use of commas for separation, Cartographica also recognizes double-quotes for string fields which may contain values that have special meaning (including d ...
5. What portions of ESRI Shape Files are imported?

For import, this means that you should (at a minimum) keep around the files that end in: SHP - the shape geometry SHX - the Sh ...
6. Can I import data from a Microsoft Access file?
   Cartographica supports importing from ODBC data sources, and with the addition of third-party drivers, this includes the ability to import Microsoft Access files. We currently recommend drivers from Actual Technologies as we have been very successful importing data using them.
7. What additional information do you put in the KML and GPX files?
   In KML, we don't add anything, because the format is not extensible, and it would lead to compatibility problems with other programs. When using GPX, LoadMyTracks can also incorporate additional data as defined by Geocaching.com and some additional pieces that have been created by ClueTrust. The ...
8. What's the difference between GPX and KML formats?
   The GPX format is an XML data format designed for lossless storage and transfer of data for GPS devices. As such, it can contain a vast array of very detailed data (such as GPS signal strength, number of visible satelites, etc). The format is available publicly from Topographix and is extensible ...
