【實用工具app】LandVector|最夯免費app-綠色工廠好玩App

LandVector is a location-based augmented reality app for measuring (estimating) land area (acreage) from the user’s point of convenience. It can also be useful for checking distances (see under Usage Steps below).

LandVector offers a tablet-optimized UI and great features for tablet users. Developed and tested using a tablet as the test device, its performance with any other particular android device cannot be guaranteed at this point. Your feedback will help to evaluate its performance across different devices.

The results are very approximate and cannot be used as final results in any precise land area measurement projects. It may be used as a tool for quick assessment of land area estimate but the results cannot be guaranteed. Accuracy depends on device sensors.

The main advantage of this app is that the user does not have to physically occupy a point to measure it. Simply stand at a location where you can see it, then aim point with camera cross-hairs and tap MEASURE button. For example, if you cannot see all property corners from one location, measure only the one(s) you can see then move to new vantage point(s) to capture remaining corner(s). This means that the user can measure a big piece of land from the point of convenience or simply by driving around and capturing the land corners or point(s) on boundary line(s) from a distance. You don't have to be at the point to measure it.

If you like the app and find it useful, please leave a review. Feature requests, comments, and suggestions are all welcome. Features will be added as customer requests, so your input is valuable.

REQUIRED PERMISSIONS:

1. ACCESS_FINE_LOCATION (GPS).

2. CAMERA.

USAGE STEPS:

There are two menu options to select from. With the first option, you can use the app to check, in real-time, ground distances to a point away from your current location, as well as the azimuth of that line. The second option allows you to estimate the land area / acreage but at this time due to sensor limitations, it cannot be used for precise land area measurements, only rough estimates. The first option can be useful for needs such as checking sighting distance in line leveling to help decide location of turning points.

For land area estimation,

1. Start the app and if it is your first time, make sure you read the QUICK TIPS that come up as a dialog when you open the app for the first time.

2. Enter the device height (i.e., your eye level height).

3. Aim target point on cross-hairs and stay on it for about ten seconds*, then tap MEASURE button.

4. If you can see all the points of interest (e.g., land corners) from one point, then repeat step 3 to measure all the points / corners. You need at least 3 or more points. The more the better.

5. If you cannot see all points from one location, then once you have captured all the points that you can see from a particular vantage point, select DONE then Select MOVE TO GET MORE POINTS.

6. At the new location, repeat all of the above steps.

7. If satisfied with all points and/or corners captured, then select option to calculate area.

*For best results, count to at least ten seconds before tapping the MEASURE button while aiming the target with the cross-hairs. This allows the sensor readings to stabilize.

SUPPORT REQUESTS:

If you need any help or quick guidance on how to use the app, or if you want to relay a comment, a question or suggestion directly, feel free to email at any time.

In case of problems with the app, keep in mind that certain responses might not help solve a problem, for example responses that simply say "doesn't work!!" or "bad app!" or any other such phrases without a brief explanation of the problem, but rather if you say exactly what happens in your experience with the app, or if you give positive constructive criticisms, questions, comments or suggestions will be highly appreciated. Also don't forget to mention the particular type of device that you are using.

Thanks for your support!
