Google Maps has set off a land invasion -- at least according to Costa Rican leaders who accuse Nicaragua of illegally charging into a disputed chunk of land both countries claim belongs to them.

Nicaraguan officials relied on Google Maps to prove where the country's border begins and ends. The satellite-based program shows the disputed land in Nicaragua.

But Costa Rican leaders say the land belongs to them.

"Anybody who's ever relied on Google Maps or a GPS turn-by-turn device has realized that every once in a while they tell you the wrong thing," explained Tom Merritt, host of Tech News Today. "They tell you to go down a street that's not there."

Google says it will change the maps as soon as possible.

The company's popular location software has caused a dispute before. In the past, Google Maps showed a small disputed island near Morocco as belonging to Morocco. But after complaints from Spain, Google changed the program to show the land as part of Spain.

Eight years ago, the island dispute almost led to a war between the countries.
