But you still do Overviews BEFORE the color balancing?

Hi all, In Pro as in Map there is a script based tool called "Add Geometry ...". The script is pretty elaborate but with a few minor changes and "reductions" it should do what you want. Find attached a toolbox with a modified sript ingested in it that (from analyzing the text above) does pretty much what you want: On a 2D FeatureClass it adds (or updates) LAT and LONG fields and writes geographic coordinates into the fields. If the fields are already present, a warning will show but the tool will run A selection on the LAT field has been added: If the field is not NULL, the calculation will not be done for that record - this should make sure existing fields are not overwritten As a default WGS 84 are set No questions asked for Units - since "nulled" the tool will write x and y in decimal degree What I didnt do: Cover all the rest of if/whens: Z,M, Other field namings, ... Took care of projections/transformations Give it a try or export the script from the toolbox and modify. All modifications to the original esri version I made can be found in the python code by searching for comments starting with #GD: Regards Guenter

Final comment - afterwards I am with you to check for a bug: Have you deleted all pyramids that might be "on" the base images? I would and only rebuild them after the whole process ... Good luck!

Honestly - there is a lot of variables in the workflow and maybe it is just a plain bug. But one thing that comes to my mind when I see the whitespace you get, is a jpeg-border-compression issue that might happen here? So to eliminate that "risk": Have you tried to avoid any lossy compression on the definitions of the pyramids/overviews/base-data? I am aware you built footprints prior to the color balancing, so it SHOULDNT matter - but who knows? Regards Guenter

I understand your wish to keep it easy for your users. As of today this is what everyone is looking for. That - to me - also includes the minimum number of layers needed ... So if your users need to have certain combination of data, have you ever tired to create a WebApp Builder App with a Query-Tool that holds prefefined queries. That way they choose from a list of "clear text sentences" like "All easy hikes in Region xy" and the complexity of selection has been hidden by you offering this query. You might end up with only a few layers and a few settings in the app that way ...

Honestly, 2500 points is near to nothing and should not pose any challenge even on the weakest hardware. Using the csv as event theme might not be ideal, no spatial indexing, no attribute indexes possible - so realy LODING the data into a FeatureClass might be better. Do you just "fear" performance issues or have you experienced them. If so, can you share the data for investigation? Regards Guenter

Hi everybody, I had recently processed a series of drone flights over densly closed forest. Hardly any ground visibility at all. Results were "sub-optimal". The first thing I wanted to improve upon were very bad height-values stored in the EXIF of the images. I luckily have a DEM and was able to improve the results (especially the location/scaling) considerably. The drone data was from a DJI 330 on a Phantom4 consumer drone. I learned that it actually only has a height value stored for the starting point and then the flight height as such. So the "individual" height values on each image were pretty off because the start-height was off. To improve, I followed this workflow: Exported EXIF of all imges in a folder to csv using EXIF-Tools (If I improve that, I'll use a python exif extractor) Modify elevation/height in csv with height from Starting point PLUS Flight height (Optionally also convert WGS84 X/Y into projected coordinate system including transformation After loading images to Drone2Map replace the elevation by reading in the csv file Process ... I have all this in python and would actually be willing to share as a toolbox - but would like to have some community-input first: Is this the way to go? Any suggestions what to include in addition? Has anyone got an idea how "valuable" YAW/PITCH/ROLL values stored by a Phantom4 are? (and how to make use of them in Drone2Map? Photoscan/AGIsoft seems to be able to read/use them) So fire away ... 🙂 Thanks

Thanks Robert, while the explanation and solution description are vey helpful and welcome - I mainly wrote this note since "we" were all used to be able to use "save as" to write out different versions of an mxd in ArcMap and I frankly sort of expected to find that feature in ArcGIS Pro, too. But the project feature will help. Thanks

I got a WGS84 GPS file in a region in Africa I have never worked in - and wanted to make a map in a suitable UTM projection. How to get it? ArcGIS Pro has a cool feature to do so: In the MapProperties - CoordinateSystems I was able to (1) set a spatial filter for suggested coordinate Systems by a layer (or known coordinates, or current extent, ...) and then search (in my case) for any UTM (2) zone that matches that area - done! I think this is a pretty cool feature - helpful and straight forward! Like it!

All i can tell you: it works fine on my machine. I had used it with Pro 2 beta and now with Pro 2.0 final.

Thanks for the reply. Yes - it requires at least Standard licensing. If you work a lot with rasters it might be worth it just because of that. Hope you have success with the procedures described by Dan and Abdullah

Hi, I was wondering: When I use the Ortho-workflows in ArcGIS Desktop (Map or Pro) I can specify a DEM I want the system to use as a reference. In Drone2Map I havent found that. Assume I do have a better DEM for my project area to start with - would it be used by Drone2Map at all? Please advise ...

‎07-04-2017

Thats actually one of THE topics 🙂 See this example in the documentation to start with. In addition, the sample Jupyter notebooks available on GitHub might help.

‎07-03-2017

I fully agree - very intuitive. Good samples and the "instant feedback" for every line of code is just great - especially for "fiddlers" who are not experienced and constant programmers

The MosaicDataset Fan is back: You should create a MosaicDataset and load both. Where one has a higher resolution than the other - it will be used - thats the simple version. There is a lot you can set as properties, too. No need to calculate them into a new dataset, if you dont want to. Though thats an option, no doubt.
