<div dir="ltr"><div>Steve: Make sure the CSV with the Lat/Longs are set to use CRS WGS84 (EPSG:4326) or NAD83 (EPSG:4269) within your project. Your Lat/Longs are showing up in Pennsylvania because they are using EPSG 2263 as the CRS and the Long/Lats are being interpreted as XY's in feet. For older versions of QGIS, to use mixed CRS's within a project, OTF (On The Fly) Transformation has to be turned on and may not be applicable in your case if you're using a newer version of the software. If whatever means of loading the CSV file does not provide the ability to set the CRS on load, it can be set after the file is loaded.</div><div><br></div><div>Right-click on the layer and go to Properties... (at the bottom of the list). Click on the Source tab and set the correct CRS. If EPSG:4326 or EPSG:4269 are not in the dropdown click on the icon just to the right and a dialog box will open. Type either 4326 or 4269 in the filter at the top and make your selection in the middle window. Once selected, press OK to close the Coordinate Reference System Selector dialog box. Then click OK again to apply and close the Layer Properties dialog box. Your points should now show up in the correct location.</div><div><br></div><div>Just an FYI that 3 decimal places in Lat/Long have a precision of approximately 350ft for your location. </div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sat, May 9, 2020 at 7:28 PM Stephen Sacks <<a href="mailto:sacks44@earthlink.net">sacks44@earthlink.net</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

<p><font size="+1">I'm mapping the location of trees and plants
along the famous Promenade in </font><font size="+1"><font size="+1">Brooklyn, NY</font>. Above a bottom layer of
GoogleSatelliteHybrid, I've drawn polygons representing 35
gardens, and then there are layers for trees in each garden,
plants, etc. The project CRS is EPSG:2263 since having
coordinates measured in feet is very convenient because
volunteers are giving me pieces of graph paper with trees, etc.
marked in pencil; each square on the graph paper represents one
foot. I want to plot all that relative to the northwest corner
of each garden. <br>
</font></p>
<p><font size="+1"> Now here's my problem. Using my cell phone
and an Android app called Lat Long, I captured l</font><font size="+1"><font size="+1">atitude and longitude at</font> each
corner. When I create a layer of garden corners they all appear
to be in Pennsylvania. I know that this forum (and many web
sites) are full of hundreds of explanations of how to reconcile
different CRS's. I've read many lengthy explanations and
advice. I'm sorry to be dumb, but I just can't bring those
corner points back to Brooklyn. I know that along my gardens
the longitude is something like -73.993 degrees (or 985217 feet)
and latitude approximately 40.695 degrees (or 193982 feet).
And the long and lat reported by my phone is close to that. But
when I put long and lat into QGIS (by reading delimited data
from a .csv file) the long becomes -77.519 and the lat 40.112
(about 200 miles west and slightly south of where they should
be). The .csv file has columns labelled "Longitude" and
"Latitude" ; the Data Source Manager > Delimited Text
window shows that QGIS got that right. </font><font size="+1">
The attribute table of that layer seems to confirm that.</font></p>
<p><font size="+1"> I've tried loading the corner points file and
then saving it as a shape file with crs 2263, but it still puts
those points in Pennsylvania.<br>
</font></p>
<p><font size="+1"> Any advice would be very welcome. Thanks in
advance for your thoughts.</font></p>
