Installation of GDAL with Conda on Windows

由 廉价感情. 提交于 2019-12-31 05:52:12
问题 I have Anaconda Python 3.6 on Windows 7. I frequently use GeoPandas and it worked fine. Yesterday I tried to install rasterio and georasters, and they seemed to install fine using the suggested method conda config --add channels conda-forge conda install rasterio Then installed georasters using conda install -c conda-forge georasters And got a successfull installation message. When trying to import them they do not work - there is an error message on import rasterio or import georasters .

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 4 years ago .

I've also seen elsewhere that running external applications, though this would be a resource in my app's bundle, is not allowed. Has anyone

I have tried following the instruction mentioned here Build Instructions for GDAL/OGR In Java (Windows) but, still I am not able to build it. I am using windows 7 64 bit operating system. If somebody has build it successfully let me know how you did it. 回答1: So, after lot of trouble I found out that that there is no need to build gdal jni from source. You can download the compiled jni dll file from here Tamas Szekeres' Windows daily

问题 I'm trying to implement the Minimum Distance Algorithm for image classification using GDAL and Python. After calculating the mean pixel-value of the sample areas and storing them into a list of arrays ("sample_array"), I read the image into an array called "values". With the following code I loop through this array: values = valBD.ReadAsArray() # loop through pixel columns for X in range(0,XSize): # loop thorugh pixel lines for Y in range (0, YSize): # initialize variables minDist = 9999 #
