Expectations of the society in public service, especially in land services, are increasing in time. National Land Agency (NLA) as government institution in Indonesia has a responsibility to fulfill the public expectations. One of the components in NLA is Land surveyors. They are the spearhead of NLA in order to give survey and mapping services to the public. The development of surveying and mapping technology is one of the solutions to increase their capability in order to meet the public satisfaction. However, land surveyors must understand the basic knowledge i.e. skills and habits of mind, tools of representation and process of reasoning to structure problems, find an answer and express solutions as defined in spatial thinking concepts. The ability to think spatially is prerequisite to use and understand the geospatial technologies. Therefore, spatial thinking is of importance for land surveyors. This research has objectives to investigate spatial thinking ability of land surveyors in NLA. To do so, first, a spatial thinking framework for land surveyors in the NLA is defined. This step is needed to specify the tasks of land surveyors and perform a literature review of spatial thinking concepts. Second, a Land Surveyor Spatial Thinking Ability Test (LS-STAT) is developed. Third, an evaluation is carried out to deliver the appropriate test. The last part is analysing the test results in relation with the land surveyor professional background. The result shows several technical tasks of land surveyors are potentially relevant with spatial thinking concepts that defined the spatial thinking framework for land surveyors in NLA. The framework is used as the idea behind the development of LS-STAT. To generate an appropriate test, student evaluation, expert evaluation, and test participant evaluation are performed. Regarding the correlation between the land surveyor’s professional background and the results, the participant having Diploma I National Land Academy (DI STPN) education background achieved the highest score. In addition, participants having 1-10 years working experience have the highest score. This thesis result is expected to be used to analyze land surveyor spatial thinking ability in a measurable and objective way.
