1. Text
[Method] Use the [Identity] tool in ArcGIS. Note: In order to count the length of the highway, the statistical operation must be performed in the projected coordinate system, and not in the geographic coordinate system. There are many ways to count the highways in each province, and this example uses only one of them.
Load data,
identify highway data,
create fields,
count the length of highways in each province, and
draw statistical histograms.
1.2 In the existing city, please use kilometer.com as the statistical unit to construct the spatial distribution map of the number of users logged in at that time.
[Method] Use the [Connect] tool in ArcGIS to achieve. Note: Create a kilometer grid network statistical unit first, and perform spatial statistics through the "layer connection data based on spatial location" function in the table connection tool.
Load data
Create fishnet
connection
Create spatial distribution map of the number of users logged in
1.3 Existing urban road data and supermarket point data, try to divide the influence range of each supermarket based on the straight-line distance to the supermarket, and count the total length of the road in each range.
[Method] Use the [CreateThiessenPolygons] tool in ArcGIS. Note: In this example, the cost is the straight-line distance to the supermarket, which is different from the road distance cost.
Load data
1) Create straight-line distance partitions,
change colors
2) Identify road data.
3) Count the total length of the roads in each district to
get the summary
