It's possible, but it depends a lot on the source you're digitizing from and the software you have available. There are tools like Esri's ArcScan but it's really only good at converting simple black and white drawings. If you're digitizing an image (air photo or satellite image), then you could use something like eCognition but it is quite expensive. Unfortunately, sometimes manual digitizing is still best!
*Sir, please tell us whether there is a very fast way to do this work, by giving a command or some classification, leaving the rest of the work on software and computer, and by itself identify the surface traits, Digitize!?*
Hello, I need your help for a school assignment. A common GIS functionality is the generation of buffer zones a) Name three areas of application for this functionality b) Name three common formats for the digital storage of geodata. c) Digitize a prepared property card for your employer. a.How do you need to prepare the scan and do you need more data? Please name two records and their geometry type, which you can derive from the scan!
Hi Eren, I'm afraid that providing you with the answers to your assignment would not really help you learn, as part of learning is knowing where to look for information and being able to sift through content to find what is relevant. I suggest you look through your course material first, to see if your instructor provided the information - perhaps in the chapter of a textbook, or a link to an online resource, such as the Esri documentation. Some if it may require you to apply what you have learned, such as the buffer question. Buffers measure distances from something, so you can think about what types of questions could be answered by knowing the distance to something (for example, noise levels from a road). I hope this is of some help, and good luck with your assignment. Don
Hello Don Boyes Thanks first for your good advice. I take note. So in my course material I find nothing really. Please help. I understood the questions but really can not find anything.
I'm afraid I can't give you the answers to your homework, as you need to learn how to do it yourself. If you can't find the answers in your course material, then you should be able to ask your instructor. You can also search the web. For example, I tried using Google to search "three common formats for the digital storage of geodata" and the first few results provided lots of information that could help you answer your question. If you search for "distance buffers examples" you'll find pages with examples that can help you answer that question in your assignment.
The term "feature class" is just a more formal way of saying a "map layer" and can be stored in a shapefile or geodatabase. I find the Esri GIS Dictionary is great for these kinds of questions: support.esri.com/en/other-resources/gis-dictionary/search/
Try searching for open data websites for your area of interest. There are more and more of them all the time. For example, here in Toronto: www1.toronto.ca/wps/portal/contentonly?vgnextoid=1a66e03bb8d1e310VgnVCM10000071d60f89RCRD
If you were following the steps in the video, then the features you created would have been stored in a file geodatabase. If you didn't create a geodatabase, then most likely your new feature class was stored in the default geodatabase - you can learn more about it here: desktop.arcgis.com/en/arcmap/latest/map/working-with-arcmap/working-with-the-home-folder-and-default-geodatabase.htm Once you find the feature class you created, you can export the data as a shapefile if you like: desktop.arcgis.com/en/arcmap/latest/map/working-with-layers/exporting-features.htm
Thankyou so much Don Boyes for your helpful video... its make my work going well for me as a newbie
You're very welcome - glad to help!
Thank you so much Don Boyes for creating such a helpful video
I'm glad it was useful!
You are my personal hero. Thank you.
Only helpful material on RUclips.... Thanks man
Thanks, that's nice to hear! :-)
Hello Don
Is it possible to digitize say for an example rivers into polygons automaticlly without doings dot digitizing to cover time? thanks
Hello sir how r u i m vry thnkful to for such a precious lec
thanks Don boyes form your useful viedos thanks a lot

great vid.Thank u Don Boyes
very useful video thnx Don Boyes
Thank You!
You're welcome!
Fantastic
Thanks Berto!

Hello,
I need your help for a school assignment.
A common GIS functionality is the generation of buffer zones
a) Name three areas of application for this functionality
b) Name three common formats for the digital storage of geodata.
c) Digitize a prepared property card for your employer.
a.How do you need to prepare the scan and do you need more data?
Please name two records and their geometry type, which you can derive from the scan!

currently im using arcmap 10.1
hey don,i got few questions, the step suppose to be like this rite?, personal geodatabase, create feature set and create feature set rite?........
Yes, that sounds right.
Thank you Sir....
Glad it was helpful :-)
thanks
Shape file and feature class are same things?
The term "feature class" is just a more formal way of saying a "map layer" and can be stored in a shapefile or geodatabase. I find the Esri GIS Dictionary is great for these kinds of questions: support.esri.com/en/other-resources/gis-dictionary/search/
how i get data for this video and others
Try searching for open data websites for your area of interest. There are more and more of them all the time. For example, here in Toronto: www1.toronto.ca/wps/portal/contentonly?vgnextoid=1a66e03bb8d1e310VgnVCM10000071d60f89RCRD
And what are you supposed to do with the new vector data created?
Whatever you like - it can be used to create your own customized map, or you could start analyzing it.
I should have electorated. How? I would like to save the vector data as a shape file but once I press save and done editing everything disappears
If you were following the steps in the video, then the features you created would have been stored in a file geodatabase. If you didn't create a geodatabase, then most likely your new feature class was stored in the default geodatabase - you can learn more about it here:

thank you Sir.
You're welcome Lucas!
