Annotation to Point
There is a case when I received the drawing from the consultant and need to generate the digital elevation model (DEM). The drawing in the AutoCAD format, and it is difficult for me since their georeferencing is not assigned. Then, the drawing needs to export to the ArcGIS for the DEM generation. Sometimes, the elevation … Read more
Create Volume Elevation Curve from DEM using ArcMAP
I got a good tutorial to create volume-elevation curve from digital elevation model (DEM) using ArcMAP .This exercise is useful if you have the bathmetric data (in term of x, y, z) of the reservoir and want to create the volume-elevation (or stage) curve. The steps as follows: You can now create a volume elevation … Read more

Add Surface Information (Z-value) to Point or Polyline from DEM
This is a good explanation on how to add surface information, which is z-value to point or polyline from digital elevation model. This is all simply done using ArcGIS, through the 3D Analyst tool “Add Surface Information“. Credit to GIS Coordinated. Alternative video (Click Here)
Adjust (such as Resize & Move) Raster Image and Shapefile in ArcGIS (Georeferencing)
This is a good tutorial on youtube, on how to georeferencing raster image and shapefile as follows. Georeferencing is the process you fix the referencing or coordinate of the raster. In simple word, georeferencing can be explained as the process you resize or move the raster/shapefile. At the end of the process, you will get … Read more
