RFID Helps Land-Surveying Agency Chart an Efficient Course

Taiwan's National Land Surveying and Mapping Center has gained visibility into each of its 200,000 maps so that they can be accessed by individuals who need to borrow or copy them.

EPC Solutions Taiwan also provided software, stored on the local server, that captures tag IDs during inventory checks, as well as checkouts. When a map is requested, a staff member uses an ATID AT870 handheld reader to locate it on the shelf and bring it to the borrowing desk, where a countertop Alien ALR-9650 reader with an integrated antenna interrogates the tag ID and forwards that data to the software, thereby indicating it is being borrowed. The employee then inputs the name of the individual borrowing that map. Once the map is checked back in, its tag is again read using the countertop reader and its status is updated as returned.

On a periodic basis, personnel will also carry a handheld reader to conduct inventory counts of the entire library. The software will record each tag ID, listing any map that might be missing. The software forwards all inventory data to the agency's existing map-management software.

More than 200,000 paper cadastral maps, which show property boundaries, are stored on shelves at Taiwan's National Land Surveying and Mapping Center.
In 2012, the solution was initially tested with about 6,000 tags, a single handheld reader and standalone software. Since that time, EPC Solutions Taiwan and the NLSC have tagged all maps and binders, installed the countertop reader for borrows and returns, and integrated the RFID-based software with the NLSC's existing software. The system was taken live in January 2015, and during the 12 months since then, it has ensured that maps can be quickly located, while inventory checks help locate any missing maps, according to Feng-Ming You, who serves as a specialist at the NLSC.

"With this RFID system, we can shorten our searching time and can have more updated and accurate inventory record," Feng-Ming states. "We are happy to have this technology."
