If you are only interested in the count, you could convert your buildings to a point feature and then run spatial join to get the number of points within your polygons. ... View more

Within your project, I suspect you may have a layer loaded or folder connection to a geodatabase that is at least 16 Gb in size (probably more if uncompressed)? Regardless of what feature is actually loaded and being used in a project, Pro will package up the entire geodatabase into a map package. Not great at all and I certainly wish they would only package up the actual features being used. I usually dont want to share my entire geodatabase with other users, just certain feature classes.  Not sure if this is your particular problem but it was mine some time back. ... View more

An alternative approach to keep your data in raster format would be to run the Region Group GP tool. This will create a new raster with a count field. To calculate size simply multiply the count field by the size of your pixels in m2. You are fortunate as your pixels are 1 x 1 m so your count field should be equal to your size in m2. Otherwise, if the pixel was say 30 x 30 m, then to determine size would be: Count x 900 (30x30).  Then run the Select Layer by Attributes tool to select those groups greater than your threshold size.  ...

You could take look at the Tile Package Kreator application for downloading world imagery (or other ESRI basemaps) as tiles packages (disconnected or uploaded to AGOL). See Tile Package Kreator | ArcGIS Blog  or https://marketplace.arcgis.com/listing.html?id=9c9ddae83e5549bb88a2c22e87a18ba1  It seems one can only create Mobile Map Packages from vector data.  ...

One can get the date, resolution and accuracy of the DigitalGlobe imagery in ArcGIS Online. Just add the world imagery as a layer (not basemap), then click on map and popup will provide date and accuracy details of the tiled basemap imagery.  ... View more

I generally use the panes to do this, not the menu bar. Right-click on the scale bar and open properties. Then click on text and there one can change the font size.  ... View more

Changing the font size of the text also changes the height or size of the scale bar. ... View more

When I have had erase or intersect tools fail with ArcMap, I usually try: Splitting those polygons with too many vertices by running the Dice tool with a vertex limit of around 20 000. Unfortunately this tool is only available with the ArcInfo license level.  Running the Repair Geometry GP tool (it is surprising how many errors creep into the geometry during a workflow) Saving to a geodatabase But I also noticed your error message referred to "Invalid Topology [M coord limit exceeded.]" You can try converting your shapefile to a new one with M Values set to Disabled under the Environment settings. It has been many years since I opened ArcMap 9.3 so what I have written above applies to ArMap 10.x but I am hoping this functionality was available In 9.3 ... View more

This is a datum issue I suspect, not a projection one. You may find that in ArcMap a transformation has been set on your data frame, but not in ArcGIS Pro. In Pro you need to right-click on the Map properties heading, then select Transformations and try and find a suitable transformation method between the datum of your basemap and that of your shapefile.  I found a great tech video from Dev Summit 2017 on introducing projections and coordinate systems here (and includes a great overview of vertical coordinate systems)  Introducing Coordinate Systems and Transformations - YouTube . Perhaps this may help. ... View more

This really depends on what shape geometry you want to create. A circle is the easiest and can easily be created using the Buffer the GP tool for a point feature and you just need to define your radius (e.g. 50 m).  ... View more

I would also like to load a raster and a mosaic dataset into a Mobile Map Package (MMPK) but it seems one is unable to do so. Only vector data or Vector Tile Packages (that also only consume vector layers) can be used to create MMPKs. It does not look like traditional tile packages are supported within MMPKs either? Is there a workaround to load rasters/mosaic datasets/image services into a MMPKs? Ideally one would want to query them but being able to load them as a tile cache or tile package would still be helpful.  Thanks. ... View more

I would recommend you take a look at this video from the 2014 or 2015 Esri UC entitled "Spatial Data Mining A Deep Dive into Cluster Analysis". It discusses Hot Spot analysis in detail.  Video can be viewed here: Spatial Data Mining A Deep Dive into Cluster Analysis  ... View more
