Dear Grid+ Support Team,
I hope you are doing well.
I have a question regarding the use of Grid+.
In my research, the estuary I am focusing on is located as shown in the first figure.
However, the grid previously created by a colleague, as illustrated in the second figure, does not align with the correct coordinates when imported into Grid+.
I would like to confirm whether it is possible to shift the grid within Grid+ to match the intended location, or if it is necessary to generate a new grid from scratch to achieve proper alignment.
I would greatly appreciate any guidance you could provide on this matter.
Thank you in advance for your support.
Best regards,
Jaeyoung An
Hi Jaeyoung An,
The Grid+ works by default with the Lat, Long coordinate system. However, it is fine as well if you have a shoreline for your study area in the UTM coordinate.
So firstly you can create the shoreline from Google Earth software, you can generate a polygon for your area. Next, you can save that polygon from GE to a KML or KMZ file. Next, open Grid+, load that KML or KMZ file by using import an overlay file feature in Grid+. Now you can zoom in on the layer by using the option from the right mouse click. It will be located at the right location on the online map. If your KML file generated in UTM coordinate, you need to define projection for it by selecting that file layer and right mouse click, then select Properties/Coordinate System/Define then choose proper projection for your area then click OK button. After that you can start generating grid.
For your existing grid from a colleague, you need to check its projection. I assume that its projection is not in Lat, Long. So you may need to define its projection when importing it into Grid+. If it’s ok you can send us your grid. We will support you.
I hope the explanation here is helpful for you.
