<font size="4">It turns out that my problem is not getting the map

=========================<br>
Original post (</font><font size="4">7/4/2022, 8:17 PM):<br>
</font><font size="4">My project CRS is EPSG:2263; all 21
layers were created in this project with CRS EPSG:2263 , which
seems appropriate for a public park in Brooklyn, NY. If I use
Google Satellite Hybrid as basemap, everything looks to be in the
right place. I would like to replace the Google basemap with one
of many maps available from the New York City Department of
Information Technology & Telecommunications (DOITT <a
class="moz-txt-link-freetext"
href="https://maps.nyc.gov/tiles/#basemap-layers-wmts">https://maps.nyc.gov/tiles/#basemap-layers-wmts</a>).
But after many tries, all I get is a totally blank layer. <br>
Here, in detail, is what I have done:<br>
<br>
1. right-click on WMS/WMTS in browser and choose New Connection<br>
2. name box: DOITT Monday<br>
3. URL: <a class="moz-txt-link-freetext"
href="https://maps.nyc.gov/wmts/1.0.0/?REQUEST=getcapabilities">https://maps.nyc.gov/wmts/1.0.0/?REQUEST=getcapabilities</a><br>
4. leave configuration default: No Authentication<br>
leave HTTP and options blank<br>
5. click OK<br>
6. "DOITT Monday" appears as a new item in browser under WMS/WMTS<br>
7. there are 15 sub-items under DOITT Monday. The CRS for each
of them is EPSG:900913 , although the DOITT web page led me to
expect 4326 or 3857<br>
8. I drag one of them ("basemap") onto the map canvas; right-click
on it and set its CRS to EPSG:2263. The project CRS remains 2263.<br>
9. I see a msg at the top of the canvas: "Used a ballpark
transform from EPSG:2263 to EPSG:900913" , which seems to me to
be the opposite of what I asked for<br>
10. the added layer appears totally blank. Toggling its
checkmark in the layer panel has no effect. Zoom-to-layer makes
the scale go to a nine-digit number. Zoom to 1:100 has no effect.<br>
11. I tried again, with a new, blank project, with project CRS set
to EPSG:900913. I added one layer by dragging "basemap" from
"DOITT Monday" onto the canvas. The canvas remained blank. I
added one small layer from my real project, transformed it to
900613, and "zoomed to layer" so as to focus on part of my park.
My layer appeared but still no visible basemap.<br>
<br>
What am I doing wrong? Thanks for any advice.<br>
