How to open WebODM TMS Output in ArcGIS Online or ArcGIS Enterprise

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...

Extract DEM from Stereo Satellite Imagery Using Agisoft Metashape

Image
Agisoft Metashape (formerly Agisoft Photoscan) is a well known Photogrammetric UAV/Drone Processing software. Using this software you can make DEM, DSM, DTM, orthophotos, orthomosaics, and 3D model from Drone / UAV survey. In the latest version, this software expanded its capabilities not only enable to process UAV/Drone Photos, but also Stereo / Tri Stereo Satellite Imagery. This feature is awesome because existing Stereo Satellite imagery processing is only can be facilitated by expensive remote sensing software like ERDAS IMAGINE, ENVI, PCI Geomatica, Socet Set. Different with dedicated remote sensing software, Agisoft Metashape can generate DEM without GCPs. Photogrammetry become more simple, altough if we talks about accuracy, that is another problem. Anyway here is my experiment and experience when I am trying the Agisoft Metashape for stereo satellite imagery processing.
