Here are the alternatives I've tried but ultimately did not work: Using the GetM() method I'm searching for a function that will return for the line_geom object and ,] for the mline_geom object. In the example above, the line_geom and mline_geom objects are successfully stored with their respective M-values, but I'm having a hard time accessing them. Mline_geom = ogr.CreateGeometryFromWkt(mline_wkt) Line_geom = ogr.CreateGeometryFromWkt(line_wkt) Here's a small reproducible example: from osgeo import ogr How can I access a line geometry's multiple M-values? Consider that the line geometry in question can be either a LINESTRING M or MULTILINESTRING M geometry that was created using osgeo/ ogr.

_core.QgsProcessingException: Could not create raster output Users/liyuhang/Desktop/Qgis/bf_2013_kde.shp: GDAL provider Cannot load GDAL driver I realize this would more simply be done with geopandas, but because of package installation issues, I cannot access that package, and am relying on GDAL/OGR. Which function could I use to carry out this table join in Jupyter Notebook? The idea would be to have an updated shapefile that I could then open up in QGIS and see the new "Value" column in the shapefiles attribute table. I am not sure if this would be called a table merge or join, or whether table is even the correct term here, since it is really a dataframe I am looking to join. In QGIS this would be a simple table join, but I am a bit confused as to which OGR python API function I should be using for this. What I want to do is match each of the census block group codes between the dataframe and the shapefile and append a column of those values over to the shapefile, matched up by census block group code. I then have a pandas dataframe that contains a column that has those same census block group codes each attributed to a value under the "Value" column. This shapefile's attribute table contains a column that contains census block group codes.

I am using the following python code to bring this shapefile into Jupyter Notebook: file_name = 'Polygons.shp'ĭriver = ogr.GetDriverByName('ESRI Shapefile') I have found seen SQL commands suggested, but I do not know SQL and was hoping there might be a simple OGR python function I could use. I am trying to join a pandas dataframe to a shapefile using python in Jupyter Notebook, and I am having trouble finding the right OGR function to do a table join. With some basic troubleshooting, it appears that the segment "dem.GetProjection()" is not returning any content but I am still puzzled as to why.any assistance is most appreciated! I am confused as to why the script runs fine as a standalone from the Spyder environment, but I get this error from within the Docker container.
: Invalid projection: +init=epsg:None +type=crs: (Internal Proj However, when this specific script is launched I am encountering an error when the processing gets to the line segment that reads "P3857 = Proj(init=epsg_zone)": File "pyproj/_crs.pyx", line 2302, in pyproj._crs._CRS._init_ My docker container was built by installing GDAL v3.0.2 and pyproj v.3.0.0.post1 among other libraries. Here is the segment of the script that retrieves the projections for EPSG 3857 and EPSG 4326: import globĮpsg_zone='EPSG:'+ osr.SpatialReference(dem.GetProjection()).GetAttrValue("PROJCS|AUTHORITY", 1)) in the Spyder environment), but I am getting errors when execute the same script inside my docker container. The script works when run as a standalone script (e.g. I am attempting to run a Docker container which contains several Python scripts to be executed in sequence, including one that converts UTM coordinates to their latitude/longitude equivalent. InputElement = driver.find_element_by_id("TEXTAREA1") This is what I've done so far: from selenium import webdriverįrom import Keys For the calculator to work, I would need to maintain the format of the DataFrame. So far I'm able to send each column separately but the problem is that the columns appear one underneath the other in the text field.
I'm trying to send the following DataFrame using Selenium into the text field of a Capital Gains Calculator website ( ). Is there some equivalent for a TAB file ?
