Here is a very useful ESRI blog you (and anyone else) who intends to link data held in Excel with ArcMap should read. It explains the many pitfalls there are with Excel. I personal avoid using Excel like the plague and get my data into personal geodatabase which is essentially a spatial enabled Access database. Much easier to read and write from and you ...

Be sure of the type of your columns (date sometimes crash) and their names (no space, no special characters). It could also be the encoding (make a try with UTF8.) or your csv delimiter.

Have you tried using Notepad as an in-between-step? After creating your excel file, copy everything in a notepad file, then choose "save as". Make sure that you change the type of file as "All files", then the name of your file must be prompted like "name.csv". (you must use " " for the filename) EDIT: yes, if you copy directly from Excel the data ...

If the data should be located in Maine, UTM 19N looks rather good: Otherwise it could be some State Plane coordinate system, depending on the state you are working in. You might have seen nothing, if you set the CRS wrongly to WGS84 (which is default in QGIS without prompting), and a Google background layer in EPSG:3857. The coordinates are out of range ...

Have you made sure that there are no other layers overlaying the view? If a raster layer for example would be over the point layer, you can not see the points because they would be physically under the raster image.

If I put your data in a text file in the format name;WKT 1;MULTIPOLYGON (((29.219629 -2.390692 0,29.219668 -2.391022 0,29.219668 -2.391265 0,29.219563 -2.391476 0,29.21951 -2.391655 0,29.219594 .... ))) it displays fine in QGIS, and can be saved as ashapefile. You need to use semicolon as separator of the delimited text. QGIS reports the geometry type as ...

The correct format for your data is not a Multipolygon but a simple Polygon with 3D coordinates 'POLYGON Z ((30.389763 -1.778877 0, 30.39029 -1.778926 0, 30.390932 -1.778926 0, 30.391557 -1.778909 0, 30.392068 -1.778876 0, 30.389763 -1.778877 0))' But as all the Z values = 0 you can use 'POLYGON ((30.389763 -1.778877, 30.39029 -1.778926, 30.390932 ...

The WKT you have there is not correct it seems, the syntax is wrong. You have a space-charakter at the wrong place. For example the -1.778877_0,30.39029 has a space, then a zero then the comma for the next coordinate pair. If this is intended and you want to have the Z-Value you need MultipolygonZ (that is not supported). Also its strange to have a ...

I can import the file using the delimited text file import button, simply chose semicolon ; as the delimiter and WKT as the geometry type. This leaves you with the simple task of finding out what the projection of the data is. I tried searching the site but my spanish isn't that good.

Let's say you have a GDB file called treedn.gdb with a table called trees and you want to export to a CSV called trees.csv. You can do something similar to this: import arcpy import csv wd = #<working directory> table = wd+"/treedn.gdb/trees" outfile = wd+"/treedn/trees.csv" fields = arcpy.ListFields(table) field_names = [field.name for ...

QGIS looks for a CR/LF at the end of each row in a .csv file. This is how Excel (and other applications) on Windows machines ends each row. On a Mac the default Excel .csv file only has a CR (i.e., there is no LF) at the end of each row. Therefore QGIS reads the file as one long row. The solution, as first suggested by ericO, is to save the file as a Windows ...

I do not think you can use Joined fields for the Start and End times. I also tested this and received the same error. This has already been recognised as a feature request. A workaround would be to save your joined shapefile as a new shapefile which will contain all the joined attributes and then add this shapefile to the Time Manager plugin.

CSV files do not contain any CRS information, just coordinates. In QGIS, take a look at Settings -> Options -> CRS tab. Under CRS for new Layers you can choose Prompt for CRS. It might be set to a default CRS of WGS84 using degrees, and if the coordinates exceed +/-180/90, the CRS will be set to undefined. Apart from that, QGIS on MAC has some ...

It's a known issue that pops up now and again with adding XY data that's been ongoing for years (see this ArcGIS Knowledge Base article): From section #3: There is a missing negative from the X field values when the values are decimal degrees (geographic coordinates). SOLUTION: Use the field calculator to add a negative to the X field's ...

Processing > Toolbox > SAGA > Vector point tools > Add polygon attributes to points: Then you select the attribute from polygon data to add: You can repeat the process with the result to add more than one attribute.
