See arcgis help: Creating polygons from lines http://resources.arcgis.com/EN/HELP/MAIN/10.1/index.html#//01m600000015000000
Marta, you would not edit your tiff images to draw polygons on them. Your tiff's are Raster datasets. Polygons are Vector datasets. You are not able to store Rasters and Vectors within the same file. What you need to do is create a new empty vector dataset to hold your polygons (such as a shapefile or a featureclass). You can then draw your polygons over ...
Go Raster->Conversion->Translate. In the output format dropdown look for either 'Erdas Imagine' or 'Standard Raster' depending on the flavour of .img you want.
I was not aware of the Rsenal package. It looks very nice and easy. Will have to take a look. What I did here was Robert Hijmans code from r-sig-geo 1 require(raster) # trmm template trmm <- raster(xmn=-180, xmx=+180, ymn=-50, ymx=50, ncol=1440, nrow=400) filename <- "3B43.980101.7.precipitation.accum" trmm <- readBin(filename, 'double', ...
I once wrote some functions to automate data download and processing of TRMM 3B42 binary data. downloadTRMM and rasterizeTRMM are included in our working group's Rsenal package. You can either install it via devtools devtools::install_github("environmentalinformatics-marburg/Rsenal") library(Rsenal) or, if installation fails (after all, it's a package in ...
I wrote a QGIS plugin that saves immediately the active layer to a .wkt file. The name of the plugin is "WktExport". You can search for it in the default QGIS plugin panel. BTW, the link to the plugin page is this: https://plugins.qgis.org/plugins/wktexport/ "WktExport" plugin for QGIS creates a folder, named "WktExport" where the original SHP is, and ...
Check out "The X3D geospatial component: X3DOM implementation of GeoOrigin, GeoLocation, GeoViewpoint, and GeoPositionInterpolator nodes" (http://dl.acm.org/citation.cfm?id=2775315&CFID=558021087&CFTOKEN=20562928 - may be pay walled).
The website http://www.maptiler.org/photoshop-google-maps-overlay-tiles/ prints out coordinates in http://epsg.io/3857 - in older GDAL it is called 900913. The website itself also contains information how to directly use the coordinates in the MapTiler software, including the variant available for free.
Universal Translator is a free MapBasic tool loaded with MapInfo. You can convert from MapInfo to various other formats. However, I have not heard of a tool that specifically converts from *.wor to *.mxd, which is what I assume you want? However, you could look at this tool for MapInfo to QGIS: ...
In short no, it is not possible to simply export and import from one to the other. All these software as also other GIS have it's own formats for projects/workspaces and especially map layouts / composers are not interchangeable at all. There are many reasons for that. Simply all software work in quite different way though there are similarities. All you ...
The PDAL GDAL reader will read any GDAL-readable raster source and turn it into a point cloud. You can then use other PDAL facilities as necessary filter and process the data.
ECMWF's GRIB API has a tool for this changing of GRIB files, called grib_set. According to example 5 at its manual page, you can set any GRIB 1 to GRIB 2 like this: grib_set -s edition=2 yourgribfile.grib And the rest of the conversion will be mostly done correctly.
QGIS with plugin Points2One seems to be the a good fit. Convert your text files to point shapefile Layer/Add layer/Add delimited text layer Use Points2One to convert to lines: I'm not sure though how it will handle 100Gb file sizes.
Since you are dealing with a rasterStack type of data you need to extract values using the extract function.The outcome therefore will be a vector. As you see in the following line, the method for the extract function is: extract(x,y,...) in the position of x you will put the raster object and in the y the locations. Then use the as.data.frame function ...
If you want to find out the co-ordinate system of your given shapefile then it is easily possible in Arcgis desktop. Simply add your shapefile in your project. Go to the property of your added layer which is in table of content. Got to the source tab. All information about your shapefile already have on data souce panal. (Including Projected Co-ordinate ...
You are defining your cursor incorrectly. You need to use the keyword with in order to work with arcpy.da (data access module) cursors. (Note that there is an old cursor , which you should not use, and a new cursor, which you should use) Here is how to set up a da cursor and print out the WKT of each feature: import arcpy shp = ...
