AMann replied to the thread Habitat Analysis with an IR modified Mavic Pro 2.Thanks for the input. You are right, a multispectral agricultural camera on any drone would have worked, but I’m just a poor student with a Mavic Pro 2. Also, as I needed to match the 1 meter ground resolution of the pre-fire NAIP imagery, even... -
AMann replied to the thread I am looking for the flight control system for a manned aircraft..Ardupilot is open source and there are a lot of commercially available flight controllers that are compatible with it. Hope you have a recovery chute on the thing- fly safe!

AMann replied to the thread Habitat Analysis with an IR modified Mavic Pro 2.Hi, and thanks for the good questions! I chose using my Mavic 2 Pro because that’s what I have…. In terms of image resolution, one can use just about any type of drone for this project since the ground resolution had to be limited to 1 meter in...

AMann replied to the thread Photogrammetric processing of a shaded valley floor.I’ve done it for quite accurate 3D modeling for a historic recordation project, which isn’t really that different from mapping. It was for a CalTrans job at a historic bridge and the shadows hid the internal structure underneath the bridge deck...

AMann replied to the thread How do you add a property outline to a picture?.If I don’t have corner coordinates and it is just an illustration, I use MS Paint - seriously! If I do have coordinates, I use either QGIS or ArcGIS. And yeah, for the title of the drawing and in the file name for it, I always use the word...

AMann replied to the thread Photogrammetric processing of a shaded valley floor.You could use HDR (high Dynamic Range) processing. It’ll take longer, but do at least two RAW mode (.dng, not .jpg) images (3 would be best) while parked at a dead stop above each photo point. Make one shot with a shorter exposure set for the...

AMann replied to the thread 4 Square mile ranch.The USGS Earth Explorer site has free 1-meter resolution geotiffs that are flown every other year. OP should look into those if all his friend needs is a map of the entire 4sq miles. They are quite good and can be paired with LIDAR data from the...

What is your friend hoping to get from this? Is this just for visualization of the property does he want absolute accuracy to include elevations for contours. Some points to think about Below 80 70 overlap (You can go lower, but with such a...

AMann posted the thread Habitat Analysis with an IR modified Mavic Pro 2 in Surveying & Mapping - General Discussion.I just finished this project for my GIS class and wanted to share the results (see attached report). If anyone is interested in doing budget vegetation mapping for habitat analysis, recovery, wetlands delineation, etc., this may be a good...

AMann replied to the thread Best Methods for Converting 8mm Film to Digital?.I’m going to get yelled at here for suggesting this on just the low technical quality of the image, but I spliced the entire set of my Dad’s 8mm and his Super 8mm films in chronological order on 2 separate reels, and set up the films to project...
