Drawing Land Using GPS Coordinates. In terms of doing depiction land by using GPS coordinates can be done in several ways, the first way is by typing directly in the autocad command or in the second way by using microsoft excel application. Both of these functions have the same goal, namely to draw plots of land in autocad using GPS coordinates. If you use the first method, a line of land parcels will be formed one by one, but if you use the Microsoft Excel application, the field drawing will be formed at once. Measuring land using the GPS point method is carried out for agricultural land, if for residential land it is expected to use meters only.
The question is, where did the coordinates of the land plot come from?
The coordinates of the plot of land are obtained from taking points directly at each corner of the plot of land using GPS. For those of you who don’t know or know what GPS is, below is an image of how it looks.
Actually, if measuring the land using GPS directly there are several advantages and some very prominent disadvantages.
Let’s start with the advantages first:
- Taking measurements is faster than using a tool, it can do tracking at the same time.
- Don’t bother carrying it everywhere because the size is not much different from a cellphone
- Drawing a field is quite easy.
The most notable drawbacks:
- The level of accuracy is very influential on the weather, it can be between 1-3 meters to the actual stake.
Those are some of the advantages and disadvantages. If you don’t have a GPS, you can use an Android phone because some types of Android are equipped with GPS. It’s just that the accuracy is likely to be better if you use a Garmin GPS device directly. If you only want to know the area of privately owned agricultural land whose size is up to 7,000 ha, it’s not wrong to try, bro. For the application, please look for the playstore. The application has a display that is quite similar to GPS and is equipped with several types of coordinates, one of which is UTM coordinates.
Here I will give an example of how easy it is to draw a plot of land using only GPS. Take a look at the picture below.
The following is the coordinate data from point P1 to point P15.
- P1 (X = 324473 Y = 1713391)
- P2 (X = 324514 Y = 1713318)
- P3 (X = 324522 Y = 1713312)
- P4 (X = 324533 Y = 1713307)
- P5 (X = 324521 Y = 1713286)
- P6 (X = 324517 Y = 1713272)
- P7 (X = 324493 Y = 1713263)
- P8 (X = 324474 Y = 1713248)
- P9 (X = 324455 Y = 1713274)
- P10 (X = 324441 Y = 1713276)
- P11 (X = 324410 Y = 1713262)
- P12 (X = 324388 Y = 1713255)
- P13 (X = 324370 Y = 1713334)
- P14 (X = 324405 Y = 1713352)
- P15 (X = 324418 Y = 1713362)
Here are the steps for using the first method in full:
At the command prompt in autocad type “L” or “line” without quotes then press “Enter” on the keyboard
- At the command prompt there will be a command line “Specify first point :” type P1 coordinates: 324473,1713391 to write the coordinates between x and y use ” ” (comma not period) and not using spaces, then press “Enter”
- At the command prompt there will be a command “Specify next point or [Undo]:” type P2 coordinates: 324514 Y,1713318 Press “Enter”
- At the command prompt there will be a command “Specify next point or [Undo]:” type P3 coordinates: 324522,1713312 Press “Enter”
- At the command prompt there will be a command “Specify next point or [Undo]:” type P4 coordinates: 324533,1713307 Press “Enter”
- At the command prompt there will be a command “Specify next point or [Undo]:” type the coordinates of P5: 324521,1713286 Press “Enter”
- At the command prompt there will be a command “Specify next point or [Undo]:” type P6 coordinates: 324517,1713272 Press “Enter”
- At the command prompt there will be a command “Specify next point or [Undo]:” type the coordinates of P7: 324493,1713263 Press “Enter”
- At the command prompt there will be a command “Specify next point or [Undo]:” type P8 coordinates: 324474,1713248 Press “Enter”
- At the command prompt there will be a command “Specify next point or [Undo]:” type P9 coordinates: 324455,1713274 Press “Enter”
- At the command prompt there will be a command “Specify next point or [Undo]:” type P10 coordinates: 324441,1713276 Press “Enter”.
- At the command prompt there will be a command “Specify next point or [Undo]:” type P11 coordinates: 324410,1713262 Press “Enter”
- At the command prompt there will be a command “Specify next point or [Undo]:” type P12 coordinates: 324388,1713255 Press “Enter”
- At the command prompt there will be a command “Specify next point or [Undo]:” type P13 coordinates: 324370,1713334 Press “Enter”
- At the command prompt there will be a command “Specify next point or [Undo]:” type the coordinates of P14: 324405,1713352 Press “Enter”
- At the command prompt there will be a command “Specify next point or [Undo]:” type the coordinates of P15: 324418,1713362 Press “Enter”
- At the command prompt there will be a command “Specify next point or [Undo]:” retype the initial coordinates of P1: 324473,1713391 Press “Enter”
After all the coordinate data has been inputted, press again “Enter” the image will not just appear on the autocad screen, the way to display the image in autocad is by pressing “Z, Enter, E, Enter” (Z > Enter > E > Enter) on the keyboard and zoom area of the autocad screen. If successful, the image will appear exactly like the example image above. It’s more complicated if you have to type the coordinate data one by one at the command prompt, or you can also use the second step.
Here are the steps for using the second method using Microsoft Excel in full:
- Please enter the x and y coordinate data into the excel cell with separate columns as shown below.
- In cell D3 use the function =B3&”,”&C3, this aims to combine 2 x and y coordinate points with a comma delimiter.
- Must add text “line” right in the cell D2.
- Block from cell D3 to cell D17, and in cell D18 add the coordinates of P1 again. so it will look like below,
line 324473,1713391 324514,1713318 324522,1713312 324533,1713307 324521,1713286 324517,1713272 324493,1713263 324474,1713248 324455,1713274 324441,1713276 324410,1713262 324388,17133255 324405731713317 ,1713391
- Copy starting from line writing to cell D18 just like above.
- Open the Autocad program then hover over the autocad command prompt
- Paste the data that was copied earlier right at the AutoCAD command prompt and press “later”
- If the above steps are correct, the whole plot of land should be drawn automatically on the AutoCAD screen. To display what was made earlier, do it by pressing “Z, Enter, E, Enter” (Z > Enter > E > Enter) on the keyboard and zoom area of the autocad screen.
Drawing farm plots using only GPS coordinates is done. and it’s time to calculate the area of the land. If you can’t calculate the land area in AutoCAD, you can read it through the link below.
