Here is the convert tool for shapefile to geojson via web browser without server-side code and supporting non-english encoding, just need to upload the zip file and set the encoding for the correctly text. https://github.com/gipong/shp2geojson.js If you use this library with Google Map api v3, you can skip EPSG code field because the ZIP ...

QGIS doesn't support text objects from TAB files. You can label the points in QGIS using the advanced label options. Pro Tip: Look at using map units for you label sizing to match how they look in MapInfo.

There is a solution to this referenced using a python script to run this bulk conversion: Conversion Solution Using Python For the most part this looks outlined fairly well, and for any bulk processes (which it seems like you are doing a lot of bulk processes with bouncing between GIS and other software) python is very useful. I would look into this any ...

Using the WMS tile service from http://lasigpublic.nerc-lancaster.ac.uk/arcgis/services/LandCoverMap/LCM2007_GB_25m_V2/MapServer/WMSServer can load the Landcover tiles in with QGIS You can save out for local files or create vector file from raster using the grass tools (r.to.vect)

The CEH data is a single band greyscale Tiff that has an Esri .lyr file associated with it to style it with the appropriate colours. This is not the most straightforward option for this dataset but it is consistent with other datasets that have multiple colour schemes. Digimap now provide a QML file along with the Layer file to make the data more ...

It's been about 5 years since I've worked with Smallworld first hand, so this may be outdated. At that time, I was using version 4.1. Smallworld itself didn't, and I presume still doesn't, have any real exporting capability for spatial data outside of it's XML which uses a proprietary schema that doesn't mesh well with GML. The only commercial option ...

I think you are seeing that particular error message from this line of your code: arcpy.KMLToLayer_conversion( r"C:\Project\gis\layers" ,r'C:\Project\gis') arcpy.KMLToLayer_conversion expects a file as its first parameter (KML or KMZ) but you are giving it a folder name. You could try concatenating the contents of your filename variable, with the ...

Thanks to tips in the comments, particularly from Chris W, I realized that the PLSS points I had were terribly inaccurate. I ended up getting proper data from the Orange County appraiser's office, by inspecting HTTP traffic while using their online map. It wasn't pretty, but the data looks perfect. In fact, the points were in the correct local State Plane ...

The only difference between LAS 1.2 and LAS 1.3 is the ability to store returns together with a references to the full waveform data. This ONLY is the case for point types 4 and 5. Most of the time people use point types 1 or 3. In this case (if you use point types 0, 1, 2, or 3) there is no difference between LAS 1.2 and LAS 1.3. If you need to "upconvert" ...

a work around would be to parse the description field for the values of the various attribute fields you need and copy them into the appropriate fields. And next time, get your client to add attributes into an excel spread sheet or something so that you can just join it back to your shapefile for updating.

Here is a guide that I found that walks you through some steps using ArcMap, Google Drive Fusion Tables, and MS Excel to convert KML files to .shp files while preserving the attributes. Link to site that has the guide.

as Bernd V suggests, it might be easier to just add the appropriate x and y offsets in excel. another possibility is to use the Affine Transform plugin (when installed, it's under Vector > Geoprocessing Tools > Affine Transform) You'd want to select all points except the O point - unless it's (0,0), in which case you should include it too. Settings would ...

Try to use ogr with python. Step 1: Open you VMAP file using QgsVectorLayer vlayer = QgsVectorLayer(<VMAP location>+"|layername=<VMAP filename>", <newLayeName>, "ogr") if you get True after you run this line it means the VMAP was properly loaded. Step 2: convert the vlayer to Shapefile vlayerToShape = ...

Unfortunately TerraScan does not have full read/write capabilities for LAS specification after version 1.2. Unless you have access to GeoCue and/or LP360, you must process and classify your pointcloud in 1.2 and then convert to 1.3/1.4 at the end. GeoCue released some documentation about this. While not specifically about 1.3, Lewis Graham discusses 1.4 ...

Shapefiles utilize dBase-III+ date values ('D' type), which are restricted to day resolution. If you need second resolution, you'll need to use a personal, file, or enterprise geodatabase. It would probably be best to round the fractional seconds to the nearest second, since Desktop's time structure (struct tm) doesn't support subsecond precision at this ...

Have you tried altering the precision in the time field to only allow "ss.s" instead of what it has there: "ss.sss"?

A very simple brute force approach: take the first points coordinates and convert them from ISN93 / Lambert 1993 to WGS84 degrees using cs2cs in the OSGEO4W shell cs2cs +init=epsg:3057 +to +init=epsg:4326 -f "%%.8f" <ISN93.txt >WGS84.txt build a local omerc CRS on that point, with the "local coordinates" as false Easting and Northing convert the ...

I defined the datum of contour lines by myself. However it was not defined by CAD programme. So I set the datum same with other vector files and offset the contours. Then I converted to dxf again. As a result, the problem has been solved

It's been a while since I tried this but it is fairly easy as GML is an output format like any other in OGR. So you should be able to take the tutorial from http://www.gdal.org/ogr_apitut.html and change "ESRI Shapefile" to "GML" compile and run it.

Generally speaking, this is called hex-encoded WKB. This specific example is the extended version, called EWKB, since it has SRID=4326 as found by E6100000. WKB can be viewed in a few forms. The hex-encoded string representation is the most common, which if it is actually text can be converted using a simple ::geometry cast: SELECT ST_AsText(wkb_geometry), ...

SimpleSVG is a Python plugin https://plugins.qgis.org/plugins/simplesvg/ --> using PyQGIS! Therefore its source code should be the perfect example of how to export SVG from QGIS.

There are several ways to accomplish what you want. You've left out some specifics such as what extensions you have available and what license level you're using, as well as how thoroughly you want to sample the raster (ie how fine is your grid). I'll make some assumptions. The simplest, if you want a point for every cell in the DEM, is the Raster to Point ...

Okay, based on the comments above. I think your first problem is that your white lines are gaps between the polygons. I would start by establishing what the subject is. I.E. is it lines on a polygon or a polygon with loads of other polygons. I would try to convert polygons to lines using Vector>Geometry tools>polygons to lines. If this works and you are ...
