Map,plan and chart are used for various significant purposes that we all know.

I'm sure we all know how important they are for decision making.

Do you know that you can produce well coordinated map, plan and chart by georeferencing??

In fact do you know that georeferencing can be use as data source for GIS database management system for sustainable land management system??

I guess you have realize how useful it is...

You are welcome! It my pleasure to share knowledge, experience and idea.
In my country will make used of RTK as well as I-Target instruments.
But for price of equipment I have no accurate idea because I haven't deal with sales and purchase of equipment.
I will appreciate if someone who has an accurate idea of price of equipment for both new and second hand to contribute to that.

Its really clear now and I truly agree with you .thanks

May be one other thing we have shortage of RTk equipments in my country does your country deal in them especially 2nd hand, coz would they a little cheaper for me and how much? Thx

With the understandable explanation, I can assure you that the accuracy of the result of the georeferenced raster map in your country will be very near accurate with a little bit discrepancy (acceptable discrepancy).
So for the overlapping you mentioned, if the appropriate reference datum for your country was chosen during the georeferencing processed then the overlapping result should be minimal.
So I will suggest that the issue of overlapping could be generated from the reference datum if you are sure of the accuracy of the coordinates of the georeferenced map.
So back to your question, I will answer that the accuracy of georefernced map is accurately acceptable when all the precision procedures are been taken care during the georeferencing process.
If there is any more you need help feel free to let me know

Archgis software...but if you could some light my country recently georeferenced all cadastral maps with the intention in mind that captured field data using existing ground control for new surveyed pieces of land would fit perfectly well in the georeferenced maps, something I was not comfortable with and indeed there were overlaps...thus the earlier question. Of how accurate is georeferenced. Data.....

What software do you intend to used for your georeferencing?

How accurate is the geographical coordinate of the rater data you intend to georeference?

Then you can predict the accuracy the coordinate of the piece of the new land

How accurate is georeferenced data when used for cadastral surveying of a new piece of land?
