GeoConverter - Free Online Geospatial Data Converter. Reads and writes several GIS vector file formats as a static ('1:1') format converter. It is based on the FWTools, especially on OGR2GR documented in the OGR page.

Rules for uploading files
This section explains the rules for uploadind files to GeoConverter:
- We use here the terms 'source file format' which is the file(s) to be uploaded and the target file format which is the file you will download as a zip file.
- There are formats like Shapefile or INTERLIS 2 which consist of more than one file. Before uploading, they must be packed together in a zip file (use e.g. gzip or PKZIP).
- If you upload a zip file, then each file inside must have the same name as the zip file itself. Example: myfile.zip may contain myfile.mif and myfile.mid.
- If you convert data to INTERLIS 2 (.xml) make sure you provide also an INTERLIS (target) model file (.ili).
- If you convert from CSV to any other format provide a plain CSV and do not provide a zip file. There is one exception where a zip file is needed, CSV to INTERLIS 2, where a (target) .ili file is has to be included.
- In addition, if you convert from CSV to any other target format make sure your CSV file contains a column header with either the column names “LON, LAT, VALUE” or “ID,VALUE,THEGEOM”. THEGEOM has to be formatted as WKT (see FAQ).
FAQ
These are Frequently Asked Questions (FAQ) as a section in the GeoConverter documentation Wiki.
- What to do when conversion fails?
- (1) Check the log file provided with the error. (2) Check if your input file isn’t bigger than 10MB. If you have not uploaded a zip file, zip it and try again. Finally (3) read the FAQ and check the rules above.
- How do I create an ili file when converting to INTERLIS 2?
- See documentation and/or contact us. Future INTERLIS 2 drivers won’t need this parameter for simple cases whereas professional conversion will need a full-fledged and configurable converter (see documentation page).
- What is WKT?
- Well Known Text, i.e. geometry values in string representation. Typical examples are POINT(1 1), LINESTRING(1 1, 2 2, 3 3) and POLYGON((1 1, 2 2), (2 2, 3 3), (1 1)). See WKT for more information.
- Why do I have to register before using this service? What are you doing with my personal information like my e-mail?
- We ask for your e-mail and name mainly because of the tedious fight against spam! As a side effect you become part of the GISpunkt HSR community where we send information mails sometimes. These mails are currently sent every other month and will never exceed once a week. Your e-mail will never be used for other purposes whatsoever and we will never give away your personal data.
- What does GeoConverter mean?
- GeoConverter means "Online Geospatial Data Format Converter".
- Is this webapplication service free?
- Yes, GeoConverter is a free webapplication and it will remain free as long as this service is not abused by daily business cases (e.g. as long as bandwidth remains low).
- Is GeoConverter a competitor to other converter software?
- There are quite some professional products around like FME, igtools or InterlisStudio. These products offer more than a straight forward and static 1:1 conversion. They can be manually configured and often support more file formats. So: No! GeoConverter is meant as an enabler of GIS and geospatial data, nothing more!
- Who runs this webapplication?
- This service is brought to you by GISpunkt HSR. It is an experimental project without any warranty.
- What are the Terms of Service of the GeoConverter?
- See here.
- Where can one submit Bugs and Feature Requests?
- Here in the 'Diskussion' page.
- Can these conversions also be run on a local PC?
- Yes: We use OGR2OGR which is delivered among others as FWTools and you can run it locally as it was designed for initially. See OGR for more innformation about this.
- Which file formats are supported by this webapplication?
- These GIS vector file formats are supported for writing and also for reading except KML:
- Comma Separated Value (.csv)
- GPX (.gpx)
- Geographic Markup Language (.gml)
- INTERLIS 1-Transfer Format (.itf)
- INTERLIS 2-XML Transfer Format (.xml)
- Keyhole Markup Language (.kml)
- Mapinfo File (.mif)
- Shapefile (.shp)
- I see GPX but can't find any other GPS file formats?
- GPS file formats like NMEA or Garmin are converted best through exiting software. See our article GPS-Software for more information on this topic.
- I miss DXF and other CAD file formats?
- Microstation's DGN (up to version 7) is supported by OGR but not implemeted yet in GeoConverter. DXF unfortunately does not yet exist as a suitable driver for OGR altough some free libraries exist - so, sponsors are welcome!
