Thanks for your explanation, it's a great video. I would like you help to solve a problem. When I try to run CA MARKOV, I get the following message : (Unexpected error condition encountered. Please check the integrity of the operation performed, the data files used, and the amount of disk space avaliable.) I have been checked all recomendations, but d'not find the problem. I would really appreciate your help. Thanks!
This is encountered due to loss in image integrity of missing files, or low disk space, or you have exhausted the space allocated to your desktop or document folder. Most times when this is encountered, make sure you are working directly from your HDD, I.e put all your raw data in on folder inside the HDD, create a working folder in the same parent folder, then make sure you connect the folder properly and ensure your result folder is correctly connected in Idris, once you get this right and you have enough space, you would not see that error again. I do hope this helps.
Hello Selam, you actually cannot Validate a predicted map on till that map year is over or past, for instance, you have done a classification for the year 2018, and have projected urban growth for the year 2020. You would not be able to validate the prediction since you have not seen or collected the image of the year 2020. But by 2021 you can validate that your prediction for 2020 was right or wrong which definitely would come with obvious reasons. Thank You.
what are the parameters we need to include except land cover map...? how many parameter such as distance to road map, slope map etc should be include? and how do we know that preediction is true?? how to validate that? please answere
You can validate your data with either a previous satellite image or through groundtruting...You go to the field and take several samples of the features then you run your error matrix using the data you have collect from the field....the percentage you get tells you the level of accuracy and validity of your processed image. thank you...you need further assistance kindly send a mail to dombo.tesini@gmail.com
The signature file you created must have been saved in a different folder that you are probably not aware of. Secondly try and work from your primary drive and not from desktop or "my documents " I.e save and work directly from drive C or any drive as labelled on your computer. That would solve the sig file missing issue

Hello Amar, you cannot clip area of interest directly on Idris, you can do that using other software like Arcgis or Envi, but you have to do this based on bands and make sure you export them in Idris format so that Idrisi can access the file format. Another workaround is by clipping your finished LULC analysis on Arcgis, then use then generate the values of features Arcgis. I hope this helps..

Kindly use window to narrow down your study area, to bring out the exact shape of your study area, you should export your result to ArcGIS where you can use ****extract by mask****** to bring out your exact ROI OR AOI. as the case may be.
You can leave it at default, but if you want your process to be fast, you can reduce the number of iterations, but don't forget, based on the algorithm and software, you might not get good results. If you are working with Envi, iterations could be set to 1 and still get good results, for Idrisi, it's not a good idea but you can try and compare results.
Validating future prediction map model would be based on several indicators as regards the area of interest, factors like capital development, agricultural development , Rate of industrialization, Urbanization and much more... thank you

hello, input lulc maps were prepared from Erdas. both images have same co-ordinate system. but after input in LCM in TerrSet, message like "spatial characteristics cannot he harmonized with the reference system is plane or incompatible with IDRIS reference system. Define a proper reference system in metadata for the land cover images" came. Reference system is 'plane' for both images, shows in metadata dialog box. Reference system for input images is UTM, Zone 45 with Datum of WGS 84. Need help.
Ok, this is simple, when exporting your data certain reference systems of the raw data is been changed from default due to the processes it has gone through using Erdas. You can use ArcGIS or Envi to correct that issue. For ArcGIS, import the data, project it to it's original reference system (you can get that information from the metadata of the original image), when you have done that, export the image band by band. Repeat same process for each bands. For Envi, import the file, then save as, select tiff and make sure the reference system is in order then click ok. Also do this band by band. NOTE: IDRISI WOULD NOT WORK WITH A COMPOSITE DATA, I.E IT REQUIRES EACH BAND AS A STAND ALONE, ONLIKE ENVI OR ERDAS THAT YOU HAVE TO STACK BEFORE YOU CAN PROCESS IT. I HOPE THIS HELPS..... having issues solving this, kindly send me a mail on dombo.tesini@gmail.com or WhatsApp me on +2348062992917

Hi Sintya, you can experience this when you have subset of different images with different row and column positions. I would suggest that you first define the rows and columns for the first image then for the second one simply use the options of *"existing window image"* so that you can have same window extents.
