The Geographic Information System (GIS) involves the hardware, software, and geographic data for capturing, managing, analyzing, and displaying every type of geographically referenced information, often called spatial data. In order to improve on the GIS skills and outputs, here are the basic tips and tricks needed;
i. Becoming a member of GIS User Network
ii. Keep Learning the GIS skills using available user manuals and video tutorials provided by the software developers and experts
iii. Analytical and Critical Thinking. ...
iv. Enhancing your basic programming knowledge in R, python , QGIS etc
See attached copy of a GIS guide, I believe this could be useful.
Wioleta Porębna, it all depends on your requirements.
Commercial soft like ArcGIS have special features if you link your Tablet PC or Graphical tablet. Your Pen works like a mouse and works in every toolbar.
QGIS mobile, free soft, is oriented to collect data and works with geospatial data in a simple interface.
Tips for Vectorization.
Set up your stream tolerance according to the time response "Pen-Tablet." Remember that it is directly linked with your work scale. Usually, in 1 stream-tolerance could work well. Also, the group points less or equal to 10 because you probably need to correct your draw many times.
I used graphic tablets just for drawing vectors in the field, like polygons or just lines in satellite images, but it works so well and quickly, not for large working (more than 2 hours).
I tried to use ESRI's ArcGIS Pro software with touch-based inputs since my laptop is an HP two-in-one device. Though I can't talk for all dedicated tablets or on the output of screen mirroring (though, Mac OS's Sidecar app works like a charm with an iPad). I would definitely say it runs on native performance as the UI isn't much different. And, would totally agree with Mr Christian Huarez as using a pen/stylus is so much comfortable than thought with these premium GIS suites, especially for drawing polygons. However, I haven't tested these feature with either QGIS or on ESRI's in-house ArcGIS Online.
