由 被刻印的时光 ゝ 提交于 2019-12-08 09:33:12
问题 I have some general questions to understand what has become a very serious issue in my project. I hope that I might come to some sort of understanding on what is happening here, as I am perplexed well over 2 months into this issue. Let me just dive in : I am in the process of making a weather app using Mapbox which displays both radar (rain) and satellite (visible clouds) over the state of Texas. I am using image overlays to accomplish this. The process is simple, but the overlays are not

问题 I am using library gdal to load a tiff file and create a shapefile. When I load my shapefile with QGIS GUI, There are no informations on the elevation. I would like to keep the elevation while the transformation. import os from osgeo import gdal,ogr,osr,gdalnumeric import numpy as np # this allows GDAL to throw Python Exceptions gdal.UseExceptions() print "reading tif file..." try: ds = gdal.Open( "file.tif" ) except RuntimeError, e: print 'Unable to open file' print e sys.exit(1) try:

Properly scale a vector to fit a raster layer

由 折月煮酒 提交于 2019-12-08 02:12:12
问题 So I've created a clipped and reprojected raster image from a Natural Earth 2 data set. It is simple enough to set that as a base layer and project a vector layer on top of it. The problem I'm having is properly scaling the images so they align perfectly. Please refer to this block for the example: http://bl.ocks.org/mkessy/8545864 Here is what I've done so far: Use gdalwarp to reproject the raster to Albers Equal Area and clip to the bounding box of North Dakota, output the image to my

Parsing osm.pbf data using GDAL/OGR python module

由 断了今生、忘了曾经 提交于 2019-12-07 12:59:32
问题 I'm trying to extract data from an OSM.PBF file using the python GDAL/OGR module. Currently my code looks like this: import gdal, ogr osm = ogr.Open('file.osm.pbf') ## Select multipolygon from the layer layer = osm.GetLayer(3) # Create list to store pubs pubs = [] for feat in layer: if feat.GetField('amenity') == 'pub': pubs.append(feat) While this little bit of code works fine with small.pbf files (15mb). However, when parsing files larger than 50mb I get the following error: ERROR 1: Too

问题 How can I get the installed GDAL/OGR version from python? I aware of the gdal-config program and are currently using the following: In [3]: import commands In [4]: commands.getoutput('gdal-config --version') Out[4]: '1.7.2' However, I suspect there is a way to do this using the python API itself. Any dice? 回答1: gdal.VersionInfo() does what I want: >>> osgeo.gdal.VersionInfo() '1604' This works on both my Windows box and Ubuntu install. gdal.__version__ gives an error on my Windows

Ubuntu 16.04 安装 Grass gis 7.6.1

由 南楼画角 提交于 2019-12-06 15:44:07
在Ubuntu上安装grassgis，最简单的方法是使用预编译好的包直接进行安装，当然也可以选择下载源码后自己编译再安装，在这里使用的是预编译包安装的方法，除了安装GRASSGIS之外，还需要安装依赖PROJ，GEOS，GDAL GRASS GIS安装 日更新的 GRASS GIS 7.x 安装包 sudo add-apt-repository ppa:ubuntugis/ubuntugis-unstable sudo add-apt-repository ppa:grass/grass-devel 2. 最新的 GRASS GIS 7.x 稳定版安装包 sudo add-apt-repository ppa:ubuntugis/ppa sudo add-apt-repository ppa:grass/grass-stable 3. 添加了ppa源之后，需要运行： sudo apt-get update 然后执行安装： sudo apt-get install grass PROJ 安装 # be sure to have an updated system sudo apt-get update && sudo apt-get upgrade -y # install PROJ sudo apt-get install libproj-dev proj-data proj
