For this week, there's an additional deliverable that was built from the previous deliverable but this time exporting your layout map showing a 3D Scene. We added a LiDAR layer to and converted it into a Digital Elevation model which gives you more than points but an image with terrain features. It helps you to symbolize it better on a map either in 2D or 3D view. The LAS point are helpful too but if you want to get an overview of the area then you need more than points and transform them into surfaces. In addition, you can make use of the building height and altitude (for GPS points) to see your resulting data draped over your terrain surface. This will help you have a real-like overview of the place without you having to be there. Wow technology is really amazing, huh?! Overall, this one is not new to me as well but it's something that I don't often do at work. We usually have it in 2D format with values but not in a 3D layout. Maybe for viewing yes but not as...

This week's module taught us how to georeference for 3 different raster data. Two of them are satellite imagery that was clipped for the UWF area. Adding raster images without georeferenced data in ArcGIS Pro will appear floating around an unknown island/area/country. To change this one must georeference the image accordingly by adding control points from image to the actual point. Tip #1 is to spread out the points for more accuracy and the number of control points can also make a difference. Besides that, we can look on the RMS (Root Mean Square) Error to determine the accuracy to the actual location. Each transformation depends on how you want your image to be shown or how distorted your image is. The higher the transformation level the more control points you need. Transformation also let you bend your raster image - again depending on how distorted your raster image is. On the other hand, besides the satellite imagery we were also give a survey data image and applied georef...

For this week's module lab exercise, we had two parts: (1) Adding XY data from an Excel file (or CSV) and geocoding an Excel file. The first part was the typical day to day life that I usually do wherein I export data collection excel reports from our data collection tools. Sometimes we use PowerBI for straight integration but both have the same concept. By using conversion formulas within Excel we were able to convert the data from DMS to Decimal Degrees. Typically, Excel files don't work well in ArcGIS desktop tools so it's advisable to have it in CSV so that you won't have any issue in the future.

I hope that this was the case in all countries especially in Asia because geocoding isn't something we use often due to lack of road/street names and information. But this is definitel...

This is where things got super interesting as we start dealing with queries and geoprocessing tools which clearly is my favorite part. For part I, I appreciated that geodatabase's importance was explained. During my days of using ArcMap, I wasn't really that aware of using geodatabases until I learned how to use ArcGIS Collector. But all throughout my college days and some years of my work I had to compile my shapefiles in folders. And yes, I tend to misplace some of the extensions which will make my life miserable. I learned to use Collector myself and one of the main component was to create a geodatabase and that's where it all started. I actually don't use the statistics tool that much in Pro but good to know that I learned something new wherein I can view statistical values instead of moving to another software like Excel. For Part II, we started using more of the geoprocessing tools like buffer, union, intersect, and erase. Our goal was to create a map tha...
