Professor Song Gao was invited and appointed as the Associated Editor for the CPGIS flagship journal: Annals of GIS  published by Taylor & Francis.

Annals of GIS is an international peer-reviewed journal that encourages the interdisciplinary exchange of original ideas on theory, methods, development and applications in the fields of geo-information science. Research papers are invited to cover the latest development in the following areas:

  • remote sensing and data acquisition
  • geographic information systems
  • geo-visualization and virtual geographic environments (VGE)
  • spatial analysis and modeling
  • uncertainty modeling

and their applications in natural resource, ecosystem, urban management, and other humanities and social science areas.

GeoJSON Conversion Issue

sgao

Some students asked me the question about the difference between Esri standard and the open standard in my course: Geospatial Big Data Analytics. The current ArcGIS conversion tool (in ArcMap not ArcGIS Pro) “JSON To Features” only supports its own format (aka Esri GeoJSON) and the structure is below: 

And it is different from the open standard GeoJSON  format from the Internet Engineering Task Force (IETF) working group, http://geojson.org/

It means that even if your GeoJSON is correctly generated, you won’t be able to convert it into a shapefile format using the ArcGIS conversion tool mentioned above.

Another option would be using ArcGIS Pro or the online tool for the conversion of open standard GeoJSON to shp:

And there are some other open source tools for the same purpose too:-)
