Upgrading Your Workflow of Field Inspection with SuperSurv


The environment of Taiwan is vulnerable. Over one thousand sensible earthquakes strike this island country annually, typhoons and the plum rain in late Spring often bring disastrous precipitation that can cause landslides and floods. Therefore, financial assistance from the government is frequently applied by landowners in Taiwan, especially farmers. The agriculture and economics division in the local government is the authority of such application. After receiving applications forms, inspectors will be sent to the site for verification. Other than the approval of financial assistance, the local government also sends workers to the field for various land management related tasks, like checking the land use, approving fallow farmland subsidy, etc.


In the past, data for applying financial assistance were mostly printed on paper, such as cadastral maps, satellite images, and application forms. Because the size of paper maps is limited, officials often need to bring a lot of papers to verify the target via reference points and to check whether the condition matches the application form. It is extremely inconvenient workflow while you are working in the field. After returning to the office, it also takes much time to organize the data acquired in the field and then enter it into the computer.


To improve this workflow, local government agencies in Taiwan seek to introduce mobile GIS software for field inspectors. The goal is to help officials accomplish their work with pre-loaded cadastral maps, road data, and satellite images, integrated into a single smart device. Also, the GPS positioning capability is necessary so that user can know where they are in the field in real-time.


To achieve the goal mentioned above, the local government in Guanyin District, Taoyuan, has decided to introduce the most advanced mobile GIS software- SuperSurv 10. Equipped with power GIS and GPS technologies, SuperSurv 10 can help users of Android devices display, collect, edit, and export spatial data, which saves the time spent on data collection, conversion, and processing significantly.

Task I Verifying the land use of specific land parcel

After a land parcel is registered as farmland in use or fallow farmland, inspectors need to check its real condition in place. For farmland in use, the official needs to record the species of crops, while for fallow farmland, it also needs to be marked.

Workflow in the Office

  1. Save cadastral maps and satellite images to your Android device and open it in SuperSurv 10. And it is suggested to create projects according to different sections so that inspectors can survey in the field more easily.
  2. Enable the label to show the Parcel ID on the map for identification.
  3. Find the target parcels with query function and mark them with waypoint function.
  4. Create a new point layer and build two custom field- Parcel ID and Condition of Crops. The Parcel ID field is designed as a drop-down menu so that users can fill it right after inspection. The Condition of Crops can be used for recording the species of crops or fallowness of farmland.

Fig. 2 (Right) Create a new point layer, customize a field for Parcel ID with dropdown menu, and enter the Parcel ID that needed to check.

Workflow in the Field

  1. Use waypoint function, and it will guide users to the target parcel.
  2. After users reached the appointed parcel, create a new feature in the point layer by the function “Add a vertex at GPS position” and record the current condition.

Task II- Checking the damages caused by natural disasters

Crops may be significantly damaged when encountering extreme weather conditions like heavy rain, hailstorm, and cold front. Farmers will apply for financial assistance. Accordingly, the local authority needs to send officials to check the real damages in appointed areas.


  1. Save cadastral maps and satellite images to the mobile device and open them in SuperSurv.
  2. Bring SuperSurv to the target area and record the actual damaged area to ensure the correctness of financial assistance application forms.
Task III- Inspecting whether the land use is under regulation

Before building agricultural facilities, the officials should check the area and the property of construction site on the spot to secure the facility is under regulation.


  1. Save cadastral maps and satellite images to the mobile device and open them in SuperSurv.
  2. Go to the target area and check whether the construction site obeys related laws.
Results & Benefits

The traditional way for field inspection in the local government heavily relies on data recorded on paper. Officials have to bring various folders, maps, and documents to the field, which often damages or loses documents and data. By using SuperSurv as an all-in-one solution for positioning and spatial data collection, field crews can integrate all needed data into their smart device and use it to complete field tasks with extra flexibility. For example, by overlaying and displaying different maps together, officials may find unexpected parcels needed to check, saving the time for conducting repeated field works. Or, the function of waypoint could help inspectors understand the direction and distance to the target quickly. The custom attribute table can help users organize the surveying data, which boosts efficiency. In addition to those features mentioned above, SuperSurv 10 has many powerful functions waiting for you to experience.
