Dec 29, 2010 QGIS Trunk 1. 7 allow you to use a Well Known Text geometry when loading data from a delimited text file. That means you Reformattiong CSV to WKT.
Ask Question. up vote1 down vote favorite. I need help reformatting a CSV file of polygons into a format readable by QGIS. The data I downloaded has a bunch of seemingly unnecessary text before the coordinates of the polygons. The coordinates are formatted like this: Chapter 4. Using PostGIS; Prev Output WKT format, for use with older (0. x) versions of PostGIS. Note that this will introduce coordinate drifts and will drop M values from shapefiles.
W Specify encoding of the input data (dbf file). When used, all attributes of the dbf are converted from the specified encoding to UTF8. Supported Data Formats QGIS uses the OGR library to read and write vector data formats, including ESRI shapefiles, MapInfo and MicroStation file formats, AutoCAD DXF, PostGIS, SpatiaLite, Oracle Spatial and MSSQL Spatial databases, and many more.
As wellknown text (WKT) representation of geometry; Refer to your PostgreSQL manual Chapter 4. Using PostGIS: Data Management and Queries; The OpenGIS specification defines two standard ways of expressing spatial objects: the WellKnown Text (WKT) form and the WellKnown Binary (WKB) form. Both WKT and WKB include information about the type of the object and the coordinates which form the object.
Output WKT format That is, the features are represented in CSV format, with the geometry data appearing in the OGC WellKnown Text (WKT) format. However, in this version of QGIS, text features from outside QGIS cannot be pasted to a layer within QGIS. This utility will convert a pseudocolor band on the input file into an output RGB file of the desired format. Tile Index This utility builds a shapefile with a record for each input raster file, an attribute containing the filename, and a polygon geometry outlining the raster.
What's the proper format for WKT linestrings when importing into QGIS? and Google hasn't been helpful. I'm using QGIS Lisboa. qgis qgisplugins wkt.

A great Wkt format qgis manual has been added to Delimited Text plugin today. It allows the use of a geometry column formatted as well known text (WKT), as an alternative to using x An Introduction to GIS Using QGIS (v. ) Author: Michael L. Treglia [email protected] com Shapefiles are one file format of vector data commonly used in GIS. The methods for most importing other vector data formats into QGIS will be similar follow the Supported Data Formats The ESRI shapefile is still one of the most used vector file format in QGIS.
However, this file format has some limitation that some other file format have not (like Geopackage, spatialite). As wellknown QGIS Documentation.
QGIS has a lot of documentation. All documentation is in Wkt format qgis manual but some documents such as the user guide are also available in other languages. QGIS Training manual. PyQGIS Cookbook. QGIS Developers Guide. Building QGIS from Source. Documentation Guidelines (how to write the docs)
