Exercise 4029. Points 2, theme: Local Statistics Along a Line
Present a drawing depicting terrain surface elevation and also minimum and maximum elevation within 10 km along a transect running from the northern end of Paljassaare peninsula to Misso settlement in the SE corner of Estonia.
Mark location of 3 ... 5 settlements or nature objects at the graph.
First, you have to get the Cartesian coordinates of the transect end points. Application XGIS from Estonian Land Board could help.
Use search by name, zoom to the location, select panel Information and click on the location in the map. Notice, that the X coordinate in European coordinate systems is the south-north direction.
In the SDC you have to select which direction is first in the input.The SDC includes a page Statistics Along a Line.
The current version of the calculator is connected to previous version of the application for courses. In 2018, you can log in using account RASAtudeng : RASAtudeng. Lidar elevation data should be available for logged in students of this course. Logged in users of the calculator can also save a limited number of transects in the server, and recall these transects later. The same transect is used in another exercise.
In this exercise the Window interval could be 1000 m, it is sufficient detailness. The buffer forms by using 10 000 m wide block kernels. It means window extent 5000 m to left and right from the transect line. Extent 500 m forward and backward will yield in kernels located side by side along the transect.
The statistics to calculate are local value, minimum and maximum.
Use Copy or Save to get the numerical results, if you like to use design another software to design the graph.
