1) Are you still searching for workflows? 2) Once you have clustered your fire events, how do you plan on analyzing it? - Zach ... View more

I'm not sure about ArcGIS Pro tools, but in QGIS, and more specifically the Geospatial Data Abstraction Library (GDAL), there is an easy way to merge with overlapping rasters.  Raster --> Merge.  You would need to create a list as a text file with the full path to ALL your 350 tiles.  The order in which they're listed determines the priority for merging the overlapping areas.  If they are all all in the same directory, we could script that in Python and call in Pro. path/to/raster1.tif path/to/raster2.tif In this case, raster1 pixels would replace raster2 pixels in the merged output. For then clipping the merged raster, that would be in QGIS/GDAL using GDAL_warp but require a Python Script most likely (as opposed to directly in the QGIS GUI).  You could presumably find similar functionality in Arc, but...not sure. It may help design a solution if you share this: export your model as a script  Zach ... View more

Didn't the right-click.  Did it!  Thanks for the subsequent post too.  I've been doing it all wrong.  Never knew about they "check syntax".  I did have an issue that my eyes weren't trained to (a string with extra quotation mark).  Now time to discover all the validation logic I messed up. ...

Adam - are you using ArcGIS Pro?  If so, I may have a solution.  let me know... ... View more

Hi Moritz.  Not an answer, but a follow up question related to your experience.  Do you find that the quality of the PNG degrades when exporting to PDF then to PNG externally.  Relative to directly exporting to PNG from ArcGIS Pro.  Much appreciated, Zach ... View more

@RhettZufelt has a nice option, but it is not interactive with the webmap open.  @JonEmch is referring to popups.  What the OP wants and misses from Map Viewer (me too!) is the ability to open the popup from a link directly in the attribute table in the webmap itself.  It's time-consuming to interactively navigate through a field collection map with attachments without that previously-available functionality. ...

Same boat.  [redacted criticism]. Would love to make it 3 days without some software issue in the ESRI universe... ... View more

Hi Luke, I almost tagged you on this post, as you seem to be the Resident Python Toolbox Expert on the forum.  That makes...more sense.  If you get time (no rush) perhaps you can use my below example as an example to point out anything I did wrong, inefficient, redundant, etc.  It's based off of your Python Toolbox sample code chunk on this post - arcpy-parameter-for-arcgis-pro-document .  There the guy was accessing layouts from a project via arcpy.mp.ArcGISProject(<project_name>). Mine has one extra wrinkle.  I am cascading the variable project_name to map_name to layer_name, ultimately updating the CIM of a layer in the execute method.  It works (took awhile). Note that I am truncating the execute codeblock for brevity. But first here is the toolbox look: import pandas as pd class ToolBox(object): def __init__(self): ''' Define the toolbox (name of the toolbox is name of .pyt file). ''' self.label = "Color Ramp Toolbox" self.alias = "Color Ramp Toolbox" self.tools = [color_ramp_from_csv] class color_ramp_from_csv(object): ''' classifies color ramp from csv. Note that user must classify color ramp simply with number \ of classes initially prior to running ''' def __init__(self): self.label = "format_color_ramp" self.description = "specify breaks, colors and labels for color ramps of rasters" self.canRunInBackground = False def getParameterInfo(self): ''' Define parameter defitions ''' param0 = arcpy.Parameter( displayName="Current Pro-Document", name="currentProDocument", datatype="GPBoolean", parameterType="Optional", direction="Input") param1 = arcpy.Parameter( displayName="Other Pro-Document", name="otherProDocument", datatype="DEFile", parameterType="Optional", direction="Input") param1.filter.list = ['aprx'] param2 = arcpy.Parameter( displayName="map", name="map", datatype="GPString", parameterType="Required", direction="Input") param3 = arcpy.Parameter( displayName="layer", name="layer", datatype="GPString", parameterType="Required", direction="Input") parameters = [param0,param1,param2,param3] return parameters def isLicensed(self): ''' set whether tool is licensed to execute. ''' return True def updateParameters(self, parameters): ''' Modify the values and properties of parameters before internal validation is performed. This method is called whenever a parameter has been changed. ''' if parameters[1].altered and not parameters[1].hasBeenValidated: parameters[0].value=False parameters[2].value=None parameters[2].filter.list=[] prodoc = parameters[1].valueAsText prodoc_selected = True elif parameters[0].altered and not parameters[0].hasBeenValidated: parameters[1].value=None parameters[2].value=None parameters[2].filter.list=[] prodoc='current' prodoc_selected=True else: prodoc_selected = False if prodoc_selected: project=arcpy.mp.ArcGISProject(prodoc) map_list = [m.name for m in project.listMaps()] parameters[2].value=None parameters[2].filter.list=map_list parameters[3].value = None parameters[3].filter.list = [] if parameters[2].altered and not parameters[2].hasBeenValidated: if parameters[0].value is not None: prodoc = 'current' elif parameters[1].value is not None: prodoc = parameters[1].valueAsText project = arcpy.mp.ArcGISProject(prodoc) map_name = parameters[2].valueAsText map_object = project.listMaps(map_name)[0] layer_list = [l.name for l in map_object.listLayers()] parameters[3].filter.list=layer_list return parameters def updateMessages(self, parameters): """Modify the messages created by internal validation for each tool parameter. This method is called after internal validation.""" return def execute(self, parameters, messages): """The source code of the tool.""" if parameters[0].value is not None: prodoc = 'current' elif parameters[1].value is not None: prodoc = parameters[1].valueAsText project_name=prodoc layer_name = parameters[3].valueAsText map_name = parameters[2].valueAsText p = arcpy.mp.ArcGISProject(project_name) m = p.listMaps(map_name)[0] l = m.listLayers(layer_name)[0]  As I said, it functions well but perhaps I missed or misused some conditions in my if statements.  I understand that altered property is re-assigned every time a parameter is changed and that hasBeenValidated relates to non-internal ArcGIS validation related to updateParameters method.  However I still don't understand WHEN hasBeenValidated is checked.  ex) Drop down, select parameter1, altered is assigned but nothing is validated?  So when does validation occur? In regards to the value and valueAsText confusion, it seems that there are loads of examples of people using it INSTEAD OF hasBeenValidated or altered.  For instance the OP in the post I referenced above, does this (line 44): def updateParameters(self, parameters): if parameters[0].value: p0Val = parameters[0].valueAsText  Couldn't it be def updateParameters(self, parameters): if parameters[0].altered: p0Val = parameters[0].valueAsText ?   Thanks for sharing your knowledge...
