QGIS Exploring and manipulating your attribute table
I swear this button was not there before I watched this video xD
I am just laughing at myself considering the amount of time I have spent wondering where is my layer styling panel. Thank you dear
Can you change the year of the basemap in case of imagery as it displays the year? If this feature is available, it would help alot in LULC
Unfortunately not, not as far as I know. The basemap is normally the latest one. However, you can search ArcGIS Online to see if your country's surveyor perhaps makes a time series of images available as a WMS.
Great content, could you please make a video on how to use coding programs to adjust and change or add tools and adjustments to the spatial software
Hi, I do not focus on the development side but you can take a look at the qGIS documentation to get you started: docs.qgis.org/3.34/en/docs/developers_guide/index.html
THANK YOU! Very helpful
I love you so much, thank you
Thank you, you saved me!
Glad I could help!

Could listen to that voice all day...
Can you teach me how to make a raster for layer transportation like what you did?
Hi. I used Euclidean Distance to determine the distance away from my road network. I reclassified into 4 classes.
how to disable/turn off the feature?
Simply click on another tool, such as Pan, or Zoom in/Zoom out and it will be deselected.
How did you scale/prepare those three layers prior to the overlay?
Yes. You have to reclassify onto the same scale before doing the weighted overlay. You do this by reclassifying the raster. Have a look here for one of the methods: ruclips.net/video/KDZr5maa6es/видео.html
I pressed the "X" on the right tab where the catalog is, and I don't know how to add it again. How do I add it again?
Just add it again by clicking on the 'View' ribbon (on the top), and then the 'Catalog pane' button. Have a look for comprehensive instructions here: pro.arcgis.com/en/pro-app/3.0/help/projects/the-project-pane.htm
Can you show how does it work the identify tool "by polygon"? I see that there is the option "Identify Features by Polygon", but it doesn't work. Because I can draw the polygon where I want to have the information, but, when I click on the right bottom for closing the polygon, nothing happens. Could you help me on this?
Click with the right mouse button until you have the polygon you want. Then right-click. Your polygon will disappear, but your features should now be selected.
@@gisatup9675 Thank you for the answer, but when I click the right bottom, the polygon disappears but the features are not selected
Apologies, you must click the outline of the polygon you want by clicking the left mouse button. You finalise the selection by right-clicking. The polygon should now disappear and your features should be selected. 1) For the normal select, left-click, hold down and draw the extent. Release the button to select your features. 2) For the polygon select, left-click in sequence to draw the outline, right-click to complete the polygon. The polygon will disappear but your features will be selected. 3) For freehand, left-click and release, draw the outline of the area you wish to select by moving the mouse on the screen (no need to click a button). When you are happy with the area indicated for selection, left-click again. Your features will now be selected. 4) For the radius select, follow the same steps as for 3), but here how far you move your mouse is indicative of the radius used for selection. Note, that you can only select features that can be selected. You must click on the layer in your TOC to allow it to be selected.
@@giovannifelici1917 did you solve the problem?
Idk, pero el ultimo ráster no te salio, que habrá pasado?
If your result is not as expected, ensure your range thresholds include all possible values. Otherwise the reclassification won't account for all values.

Can you create a simple base map from scratch?
Yes, but you would have to add all the layers yourself and symbolise them appropriately. You would need, for example, a road layer and other transportation lines (like railways), towns and cities, and some kind of background. The background is not entirely necessary - it depends on what your need is.
@@gisatup9675 I'd like to create a very simple base map: The entire globe with all land mass as white and all water bodies as blue. Simple. No roads, rails, cities, populations, etc. I can't seem to figure out how to do this very simple thing. Any tips?
That is simple. Download a world country layer - simply search for 'world country layer' or 'world country feature class'. Add the layer to your map and symbolise appropriately. You can use a dark outline and a white or light fill, or a grey fill with a light outline for the countries. If you want to show only the continents download a continent layer instead. Then make the oceans look blue by giving the map a background colour. So you basically only need one layer to make this basemap.
@@gisatup9675 I'm new to ArcGIS Pro and it's very confusing. Where and how do I search for the world country layer?
👍
Tool not visible by default, there are more steps to get to where you are.
Hi, this video was created on an older version of QGIS. The newest version has more functionality (including the 'Measure Bearing' option). If the tool is not visible, go to View>Toolbars and activate (tick the check box) next to the 'Attributes Toolbar' option.
I have uploaded an image which is a map, and I have created many text annotations, but I want to search for one and cannot."
If the text annotations are graphics, you won't be able to search for them. Ensure they are stored as labels (attributes describing a geographic feature), to ensure you can search them.
How do you change the spatial reference/projection to NAD1983 StatePlane New Jersey FIPS 2900 (US Feet)??? Thanks
You can't change the projection of a basemap but you can change the coordinate system of the map. Change these by clicking on the arrow in the middle of the screen, where in the video it shows 99.99.... Wm, 15....N. You will have the option to choosing any CRS and the basemap will adapt to what you set.
Great video....That was helpful. I had a question though. Is there any way to create contours from point feature classes? If you know please make a video about that. And thanks a lot for this content!!
Hi. Contours to my knowledge can only be created using a surface elevation raster. You would first have to interplate, and then generate contours using the Create Contours tool. QGIS has a way to do this directly. Use the install the Contours plugin to do so. It is nicely described here: www.geodose.com/2018/05/how-to-create-contour-lines-in-qgis.html
@@gisatup9675 Thanks a lot!! I am checking what's in the link!!
Thanks.
Glad it helped.
Great vid, what was the preferred method you mentioned? Didn't quite catch what you said, thanks!
The built-in georeferences (the GDAL option) is a better option. It is more accurate and allows a statistical evaluation. You use this tool when you can't get the image to georeference correctly when using the GDAL option.
Thanks so much
Glad it helped.
Thank you for sharing!
Glad it helped.
What do you if the Identity Features has disappeared as a function from the screen and no longer works?
Do you mean it is not longer visible on your toolbar? Make sure the Project Toolbar is active (tick box checked) under View > Toolbars. The tool will also not work if you don't have geospatial layers added to your project. For example, if you have added a CSV or txt file, then it will be grayed out, since there is no geospatial component to such files. First create a geospatial layer, or add one, to use the tool.
@@gisatup9675 It seems like a bug maybe. It was the 3.32 Lima Version. Not the 3.28 Firenze. Cause it stopped working in terms of being able to click on the shp file with my arrow for information. And I used the project toolbars and views ... still not working. So I decided to delete it for now and work on 3.28 instead. A more stable version. There the Identity Features does appear.
Exactly what I was looking for, thank you very much for such a simple and effective explanation! 👍
Glad the video helped!
Could you please give up short link's
Hi. This is actually quite an old video. You can install the QuickMapServices plug-in and access quite a number of great basemaps through that without having to manually add the URLs. Once you have installed the plug-in, navigate to its settings ('Web' menu > QuickMapSerivices>Settings) and select 'Get contributing pack' (under the 'More Services' tab).
Is it possible to do this with multiple tables at the same time in a model?
You can try the Iterate Table function.
@@gisatup9675 Not sure if this works, because I have a ton of standalone tables and not a workspace. Might there be some way to circumvent this?
@@lieuwedewolf2476 In this case it might be easiest to run a script in ArcPy. Load the folder, load the tables into a list, and go through it to display the XY data. End the script when the list ends.
Hi, Is there any way I can change XY coordinates showing at bottom of your screen from WGS1984 to GDA2020 or other system?
The information displayed on the map project is the current CRS for the project. If you change the project CRS, that information will also change. You can set a project CRS from a layer (right-click), or via the Catalog.
@@gisatup9675 cant find change crs option in arcgis pro, i did find that in arcmap 10.x versions
@@avaiyajigar3503 Hi! You access the functionality under the Map Properties dialog. Have a look here: pro.arcgis.com/en/pro-app/latest/help/mapping/properties/specify-a-coordinate-system.htm
Thank you so much that was very helpful, I really appreciate your help GOD bless
Glad it helped.
Glad it helped.
thank you for contribution, but i have questin rised, i'm cliking on the editor tools, unfortunately it's not visible
Dear Eric. ArcMap is no longer supported by Esri so it is best to move over to ArcGS Pro. Ensure you have selected a template layer to edit.
thank u so much
Thank you for posting 🤙
This was sooo helpful, thank you!
This helped me. Thank you :)
Thank you for your helpful video
Very good video! How can I access that raster data? Thanks
Some of the layers were created, but many are freely available. The landcover layer can be obtained from the Department of Forestry, Fisheries and the Environment of South Africa. The website is egis.environment.gov.za/

if processing toolbar panel not present... then how to insert processing toolbar
Go to Processing (top menu) and click on Toolbox. Otherwise go to View (top menu) > Panels > Processing Toolbox
Great video, thanks :) Unsure why this was never covered in my GIS lectures, but it was simple enough to understand from yours!
What grey area you talking about
Thanks
Main parts of GIS DATA model are SPATIAL data and attributes data or TIN & DEM?
