WebODM (web Open Drone Map) is a suite of Open Source UAV/Drone-based photogrammetric processing software running on the server-based infrastructure. This software is developed to provides UAV Photogrammetric Mapping Services over the internet using Server-Client architecture and clouds based computing engine. If you are familiar with Pix4D clouds or DroneDeploy, this software offers similar services, only it is free-to-use and open-source licensed. So you can also contribute to the development.  Personally, I have known this software for quite a time but didn't have time yet to learn deeper about it. Recently my some guys in my office have been successfully deploying this software so finally, I can start to use this software more regularly. Basically, this software is on par with its commercial counterparts like Pix4D or DroneDeploy. WebODM also has an API REST Interface that enables us to integrates the services with the geoportal system (either open-sourced like Geoserver/Geonod...

Vegetation cover data is one of the most important biophysical parameters that can be effectively and efficiently extracted from Remote Sensing Satellite Imagery. A wide range of vegetation cover extraction methods have been developed since years ago, ranging from indirect regression using NDVI data and field measurements, greenness index conversion, and many others. These methods can give vegetation cover information in raster format that can be used for many kinds of applications. For example, you can incorporate vegetation cover data as additional input for biomass estimation, soil erosion modeling, vegetation cover multitemporal analysis, et cetera.  Vegetation cover is best estimated using low to medium-resolution satellite imagery. On this one, these days we have so many options of satellite images, and most importantly, they are mostly free to use and free to download. LANDSAT, ALOS AVNIR, SPOT 5/6/7, SENTINEL-2, MODIS, ASTER just name a few of them. Specifically for LANDSAT...

ArcGIS has tons of features, not only about its GIS capabilities, but also other useful tools for many purposes. Some of the tools are usually hidden by default for the GUI simplicity, but once we know how to activate and use those tools, you will be surprised how handy these tools are.  for example, I am sure not everyone knows that ArcGIS has an internal color picker tool called eyedropper tool that can be very useful for Cartographic Production. All the cartographers going to needs this tool because it will enable color peeking of finished maps or cartographic products either in vector or raster formats supported in ArcGIS. For example, if you are interested in the online base map color composition currently loaded in the Map View, you can extract the RGB color information using this tool, and re-apply the color into your own map using the symbology tab.  So, if you are interested in how to get the tool, I have made a super short video showcase (one-minute duration) below....

Database View is one cool things about database management in DBMS. Using database view, you can deliver so many options of data publishing without messing up your database and messing up your tables structure. Database View is a common features that almost every database platform could have that features, includes here is spatial database (PostGIS, Oracle Spatial, or Enterprise Geodatabase).  If we talks about database view in Enterprise Geodatabase, it has all the features of enterprise geodatabase feature class. Database view in Enterprise Geodatabase is also directly linked with its parent tables. So any modification or updating in parent tables will also reflected in the database view. The database view itself is read only and only support reading/view.  Database View as I already told actually is one of the DBMS features regardless what kind of DBMS are used. If we see it in Enterprise Geodatabase Point of View, Database View when it is just created or imported, is not c...
