How can I cut a part out of the map shapefile?
I have one ESRI Shapefile as a map with many objects in it. I have another ESRI Shapefile only with borders in it. This shapefile is bigger in size (covering a bigger area) with many border lines. The border lines form many mosaic pieces (tiles). How can I cut a part out of the map shapefile with the border shapefile as one mosaic piece?
What to do with border shape files in ArcGIS?
With it, you can use the border shape files to “cut” through and divide the other shape file. Assuming that you are using ArcGIS 10 then you can use the Clip Analysis.
Is there a problem with the shapefile data?
Problem is, like most map data sourced from third parties, this Shapefile contains features and information outside of your area of interest – in fact, it contains geometry and attributes for every single US county. If you’ve ever downloaded a shapefile from the US Census Bureau’s website, you’ll find this is a common problem.
Where can I find shapefiles for administrative boundaries?
You can easily find Shapefiles for different administrative boundaries for free online. For example, the administrative boundaries for the U.S can be downloaded from the Census Bureau. We will be filtering the data using a popular open source desktop GIS ( geographic information system) program called QGIS.
How to split and clip shapefiles in QGIS?
Open both shapefiles in QGIS. In the main menu, select Vector -> Geoprocessing Tools -> Difference. Select the municipality dataset as “Input vector layer”. Select the sea areas dataset as “Difference layer”.
How to intersect two layers in geoprocessing tools?
Intersect the two layers (Vector|Geoprocessing Tools|Intersect), with the first layer as the original shapefile and the second as your vector grid. The output will be your shapefile chopped up by the boundaries of the vector grid. I am assuming that the grid you refer to is a spatial grid of some regular size – 1×1 km or similar.
Can you divide a shapefile into regular rectangles?
Anyone can help or know a nice function? Using QGIS you can quickly divide a given shapefile up into regular rectangles as you’ve shown in your example.
