Abstract
In the article, space images when compiling various maps for remote sensing, when
you need to create a thematic map of a particular area, enough information can be
obtained from remote sensing signals in a short period of time. This speeds up card
production and improves accuracy. The use of remote sensing technologies in crop
mapping greatly simplifies the mapping work.
Description
Also, crops usually do not grow evenly across the field, and as a result yields vary from place
to place. This difference in crop growth may be due to a lack of nutrients in the soil or other
factors. Remote sensing enables farmers to identify crop problems in the field and provide
these crops with the necessary nutrients, pesticides and herbicides. With this method, the
farmer not only increases the productivity of the land, but also achieves financial savings
and reduces the impact on the environment.
Remote sensing can also monitor variable growth in crops located in the same field. Healthy
crops appear uniformly light in color, while infected crops appear darker than healthy crops.
If the data is georeferenced and we have a GPS device, we can very quickly locate the problem
location by matching the local coordinate with the image coordinate.
Remote sensing is used in mapping for the following purposes:
• Creating a contour map;
• Creating a digital elevation model (DEM);
•Making the main thematic map, making a topographical map.
There are 3 main methods of mapping in remote sensing and area monitoring:
1. Field imagery-gathering data using geodetic measuring instruments, observation and
location maps.
2. Taking digital pictures of the Earth's surface with the help of equipment specially installed
on aerial photography devices (planes, helicopters, etc.).
3. Spatial imaging - taking pictures of the Earth's surface with the help of special equipment
installed on space apparatus (sputnik).
Based on the information given above, it can be said that the information obtained by remote
sensing serves as the most convenient source in every field, because we can get an effective
result by spending less time on the information we receive. This creates great opportunities
for effective use of limited resources. Especially in the fields of agriculture and water
management, the use of remote sensing materials will make mapping easier.
