zulkarnainh 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

Special thank you to the chair and organizer of the presentation to manage this presentation, namely Dr Norazian … Read more
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
One of the main limitations of SDSM is the lack of multiple GCMs for the AR5 RCPs. To gain insights into climate model uncertainty for different RCPs,we can deployed the NEX-GDDP data (https://cds.nccs.nasa.gov/nex-gddp/). In NEX-GDDP data, different RCPs are deploy and can be compare to the projection from the SDSM model. Reference: Daksiya, V., Mandapaka, … Read more
The following workflow uses the IN query operator to select multiple values. This workflow is also applicable to the other query operators, LIKE, OR, and NOT.
