How is the clip tool different from the intersect tool in terms of how it works or the result? I don't have a specific situation in mind. I was learning about each of these tools and was curious about how they differ since the results seem to be very similar at first glance. The main difference will be in the attributes of the results.
There has been a recent trend towards questions asking for an explanation of the differences between tools. In this case you will find that the Intersect tool will create output features which possess the attributes of all input features. Note that there can be multiple input features.
The Clip tool only allows for one input feature and one clip feature and will therefore only output features containing the input feature attributes, not the clip features. Has an impact on geometry and attributes both layer attributes inherited too. The Clip is a complex method collecting every touched in Geomedia or intersecting in QGIS, Spatial Query features in clip polygons, and save them which does not effect the geometries and the attributes neither. Touch returns features that touch the defined features in any way—meeting, overlapping, containing, or being contained by.
The output point features are where a polygon from one of the input feature classes has a vertex intersecting the boundary intersect at a point of a polygon from the other input feature class. When all the inputs are line feature classes, the intersect tool can be used to determine where the features from the input feature classes overlap and intersect at points and lines. Line inputs and line output.
The output line features are where a line from one of the input feature classes overlaps a feature from the other input feature class. The output point features are where a line from one of the input feature classes crosses a feature from the other input feature class.
When all the inputs are point feature classes, the Intersect tool can be used to determine which points are common to all input feature classes. Integrated mesh and 3D object scene layer packages must use I3S version 1.
Use the Upgrade Scene Layer tool to upgrade version 1. The output scene layer package will be in the latest I3S version.
This tool will use a tiling process to handle very large datasets for better performance and scalability. For more details, see Geoprocessing with large datasets. Line features clipped by polygon features:. Point features clipped by polygon features:. Line features clipped with line features:. Point features clipped with point features:. Attribute values from the input feature classes will be copied to the output feature class. However, if the input is a layer or layers created by the Make Feature Layer tool and a field's Use Ratio Policy is checked, then a ratio of the input attribute value is calculated for the output attribute value.
When Use Ratio Policy is enabled, whenever a feature in an overlay operation is split, the attributes of the resulting features are a ratio of the attribute value of the input feature. The output value is based on the ratio in which the input feature geometry was divided. The clip tool is an overlay function that cuts out an input layer with the extent of a defined feature boundary. The result of this tool is a new clipped output layer.
If you can picture a cookie cutter, this is like using the clip tool. And carving out vectors and rasters is one of the most common operations in GIS. To clip data, you need points, lines, or polygons as input and a polygon as the clipping extent. The preserved data is the result of a clip. You can even find the Sunshine State on their license plate. But how much sunshine does Florida really receive?
It turns out that global horizontal irradiance GHI is a good measure of incoming solar radiation. So if you wanted to install a solar panel, GHI is the recommended data set.
If you clip GHI to the Florida state boundary, you can really find how much sunshine Florida really gets. The merge tool combines data sets that are the same data type points, lines, or polygons. When you run the merge tool, the resulting data will be merged into one. Similar to the clip tool, we use the merge tool regularly. For merging, data sets have to be the same type. For example, if two grocery store giants like Ahold NV and Delhaize Group want to combine their 6, stores, we can use the merge tool.
In this case, we have two existing data sets from both companies. The merger between the two grocery stores into one company — Ahold Delhaize — means all grocery stores will be combined into a single data set.
When you combine grocery stores points from both companies, they all end up in a final data set. The dissolve tool unifies boundaries based on common attribute values. In other words, dissolve merges neighboring boundaries if the neighbors have the same attributes. For example, if you want to remove the borders of countries to form a continent, the dissolve tool is the tool to use.
But you would need an attribute for each country and the continent it belongs to. What do Germany , Yemen , Tanzania , and Vietnam all share in common? They are all examples of two countries dissolving their borders and unifying to form one. Country unification is a rare event. But dissolving boundaries in GIS is not.
The dissolve geoprocessing tool erases borders and unifies them into one. When each country has its continent name in the attribute table, you can run the dissolve tool to unify borders into continents.
Over 25 years ago, the Berlin Wall was wiped away which divided East and West.
