This section contains a brief description of the tools available in the UTM Geo Map application and how to use them.
Trim Polyline Inside / Outside Polygon
This tool allows you to trim a polyline inside or outside selected polygon.. read more..
The smoothing process produces a curve like geometry that looks smoother than the original object and is cartographically beautiful. Smoothing is usually applied to contour lines, but can also be applied to any lines and polygons features.. read more..
This tool allows you to reduce number of vertices on polyline or polygon features by defined distance tolerance.. read more..
Fixing Invalid Polygon
UTM Geo Map will automatically detect polygons with invalid geometry when it clicked and ask you whether to fix them automatically or not.. read more..
Converting Points To Line Or Polygon
This tool allows you to generate a linear or polygon feature automatically from existing points data. For example, you can load a set of collected points from a global positioning system (GPS).. read more..
Centroid and Interior Point
The centroid is the center point or mass of the object. In GIS work, we are often asked to create points inside a polygon for placing the database or other purposes.. read more..
Extract Vertices is a tool on UTM Geo Map APP for Converting vertices from lines / polygon feature to point features. This is another usefull tools in GIS, for example for detecting pole possition from power-line features.. read more..
UTM Geo Map can be used to create points at the intersection between lines and / or polygons. This point is quite important in GIS and is used quite often, for example to find the location of the intersection of road networks, pipelines and so on.. read more..
Delete Contours Inside / Outside Polygon
UTM Geo Map is equipped with a module for creating contour lines through the Contours module, this module is also equipped with the ability to perform contour editing such as to delete or cut contours inside / outside polygon automatically.. read more..
Buffer is a polygon boundary that is defined with a certain distance, usually used for spatial analysis such as the spread of disease, waste, flood areas etc. Buffering is very important in spatial geometry analysis.. read more..
Split Polygon By Line
Splitting a polygon by an overlapping line / polyline feature is a very useful tool, for example you can use this tool to separate a forest area using a river or road line.. read more..
Delete Points Inside / Outside Polygon
How to count the number of points inside or outside a polygon? looks easy but will be difficult if the number of points is large or the polygon shape is complex.. read more..
Count Points Inside / Outside Polygon
In mapping work, we often encounter cases where we have to delete points that are inside or outside a polygon, for example deleting all DTM points that is inside a building polygon or deleting all points that is outside the polygon project boundary.. read more..
