Hallo, würde die Frage glaube ich woanders stellen (vielleicht im Datenmanagment?). Ich würde auch die Ausschreibung nicht so vornehmen. Die UAV Befliegung und die Orthobilderstellung haben ja erstmal nichts mit ESRI Produkten zu tun, und nicht jede Befliegungsfirma arbeitet mit ESRI Produkten. Du raubst damit vielen Anbietern die Möglichkeit mitzubieten .... . Ich würde das also auftrennen in Befliegungsdaten und Datenmanagment? Grüße Johannes

Don't know if I understand you right, but there's a tool "add surface information" in Spatial Analyst? Maybe you can use it to add the information of the geotiff to your feature class of buildings? https://pro.arcgis.com/de/pro-app/latest/tool-reference/spatial-analyst/add-surface-information.htm

Hello, i've slightly adapted a script of Bera - Stackexchange - https://gis.stackexchange.com/questions/308705/split-a-line-at-a-specific-elevation It should set a point every 10 cm hight change on a line. The script is somehow working but not very efficient, is there a better way to do it? Originally the script was for one best point on a line ... How not to write single bestpoints to fclass? Any ideas? # erzeugt Punktshape alle x cm Hoehe entlang Linie
import arcpy
import numpy as np
arcpy.env.overwriteOutput = True
arcpy.env.workspace = r"Path\Berechnung_4.gdb"
fc = r'Path_to_FGDB\Gew_Morre'
inDGM = r"Path_to_FGDB\dgm01m"
step = 1 # 0.1 in script - Change, as small as possible without making the execution time unacceptably long
arcpy.CheckOutExtension("3D")
Gewaesser_3D = "Gewaesser_3D"
arcpy.InterpolateShape_3d(inDGM, fc, Gewaesser_3D)
arcpy.AddSurfaceInformation_3d(Gewaesser_3D, inDGM, "Z_MIN;Z_MAX", "BILINEAR")
arcpy.CheckInExtension("3D")
with arcpy.da.SearchCursor(Gewaesser_3D,['SHAPE@','Z_MIN','Z_MAX']) as cursor:
for row in cursor:
print("valueMin = {} and valueMAx = {}".format(row[1], row[2]))
arr = np.arange(row[1], row[2], 0.1) # hier Hoehenstufen definieren!
print(arr)
for r in arr:
geom = row[0]
points = []
position = 0
while position < geom.length:
points.append(geom.positionAlongLine(position))

Hello, we have a concurrent license model on a seperate server. We are only allowed to check out the advanced license for the needed time ... . In arcpy ArcMap you could set the product temporarily very easy, in Pro 2.8 notebook this doesn't seem to work with check product in our case. There's always the message "ArcGIS for Desktop Advanced license not available" even if more than one license is available with the following code? import sys
import arcpy
arcpy.env.workspace = "c:/data/world.gdb"
if arcpy.CheckProduct("ArcInfo") == "Available":
arcpy.PolygonToLine_management("Lakes", "LakeLines")
else:
msg = 'ArcGIS for Desktop Advanced license not available'
print(msg)
sys.exit(msg) Does this work only with licenses saved online? Are there any workarounds? It would be very uncomfortable to check out the license manually in Pro every time the advanced license is needed ...

Thank you for your good idea. It leads then to something like this (if I build a model and export to python): arcpy.analysis.Select(in_features=outUnion, out_feature_class=outUnion_Select, where_clause="FID_Nutzung_Weide > -1 And FID_outBarriereBuffer = -1") but doesn't work in the notebook. Think I will use the select by attribute + copy feature solution to get to an end ...

If I use select layer by attribute and copy feature there is no problem? arcpy.management.MakeFeatureLayer(outUnion, outUnionLayer)
arcpy.management.SelectLayerByAttribute(outUnionLayer, 'NEW_SELECTION',
'"FID_Nutzung_Weide" > -1 And "FID_outBarriereBuffer" = -1')
arcpy.management.CopyFeatures(outUnionLayer, outWeide)

I have problems in ArcGIS Pro 2.8 notebooks with a where clause of two long fields of a file geodatabase feature class (FID fields after union): where_clause_1 = '("FID_outBarriereBuffer" = -1 AND "FID_Nutzung_Weide" > -1)'
arcpy.analysis.Select(inBarriere, outWeide, where_clause_1) With this I get the following message: ExecuteError: ERROR 000358: Ungültiger Ausdruck ("FID_outBarriereBuffer" = -1 AND "FID_Nutzung_Weide" > -1)
Fehler beim Ausführen von (Select). Any ideas for a solution?

Hello, I've problems with the "MULTIPOINT" option in arcpy.ASCII3DToFeatureClass_3d, it creates stranges results in the outgoing fc. See attached image in red there are squares create with the wrong hight information out of lidar vegetation (first pulse) data. In the image I analyse vegetation hight over 3m. If I use the "POINT" option the vegetation is correctly shown in the output raster data (black in the image). What's wrong, can't you use "MULTIPOINT" with lidar data with a resolution of 8 points/m²? Is it a bug? It takes very long time to process the data with the "POINT" option ...
