From Autodesk Map 3D Online Help: Importing MapInfo TAB Files You cannot import TAB symbol types directly. However, if you store the symbol type information in a column in a DAT file, you can map each symbol type to a block in the current AutoCAD Map 3D drawing. To do this, prepare the TAB file by putting the name of the symbol type into a field ...
I had the same problem of QGIS reading a CSV file (saved from MS Excel 2011 on my Mac) as a single row. So, I re-saved the Excel worksheet as "Windows Comma Separated (.csv)" and QGIS was able to read it just fine.
You can use this tool https://github.com/openAIP/airspace-converter to convert the airspace data to openAIR format. QGIS is able to import data in openAIR format. If you only need data for a specific country, contact me. I can give you access to the shapefiles for the particular country. openAIP version 2 will also provide shapefiles.
I was unable to resolve this. No matter what version of QGIS I used, no matter how I formatted the ExtendedData, I was unable to get it to import this data. So I found a work around. My end goal is to save the KML file out of QGIS as a shape file to send to my client after I had manipulated it. So based on this post about converting a KML file to shape ...
Well, as far as we got now, I would say that it is a bug. I am still confused a bit as it works in the python window with *.xls files and *.xlsx files, but not using a stand alone script. I solved the problem now, as I import the data from the *.xls file to python using xlrd and export it to a *.xlsx file using xlsxwriter. Maybe not the smartest work around, ...
I don't know how much or what type of information you have in your .CSV, but I looked at files of mine which for instance hold over 500,000 streets (polylines) where the .DAT file is 90MB and another file with 2,500 cities (polygons) where the .DAT file is only 400KB. If you'd like to send me the .CSV I can covert it to .TAB for you through MI and see if I ...
You can use the build in import plugin that is installed when you install the PostGis extension in PostGres You can find it under Plugins in the menu and is called the PostGIS Shapefile and DBF loader watch this youtube video as an example
I have also noticed that QGIS up to my current version (2.12.2) appears to have a problem loading MSSQL geometries of type "GeometryCollection", when you would expect Polygons or Multipolygons. To check if you have these, use: SELECT GEOM.STGeometryType() FROM [yourtable]
You could run the Refactor fields tool from the Processing Toolbox to change the field type once you have added your .csv file to QGIS: You can save this as a new shapefile and use this for your heatmap analysis.
Edit: You can enforce the data type behaviour you want with "Add delimited text layer" using a CSVT (my previous statement was it wasn't possible at all but due to Alexandre Neto feedback, I changed my answer) You can follow this blog post to learn about CSVT files. You can also add your CSV file with "Add Vector Layer" and use a CSVT file again.
