<![CDATA[Agricultural land inventories require reliable spatial records, accessible software, and consistent data validation. This study assessed AgriMap Field version 1.2, a self-contained offline web mapping application, through a computational simulation designed to examine its evaluation procedures before field deployment. A structured simulation dataset comprised 30 hypothetical user profiles, 120 task attempts across four inventory activities, 30 ten-item System Usability Scale (SUS) response sets, 30 agricultural plot records, and paired geographic coordinates. Task completion was assessed using recorded success and a stricter definition requiring completion within the specified time without assistance. SUS scoring and internal consistency were recalculated, and coordinate-pair distances were independently verified using the haversine formula. Recorded task success was 88.3% (106/120), while strict independent success was 80.0% (96/120); spatial location retrieval had the lowest strict success (70.0%). The simulated SUS mean was 73.0 (standard deviation 9.01), with Cronbach's alpha of 0.774. All 30 simulated inventory records contained the six mandatory fields, and the mean distance between paired coordinates was 6.43 m; 25 of 30 pairs were separated by less than 10 m. Separately, all 61 predefined software regression checks passed. These findings support the internal consistency of the evaluation framework and identify mapping navigation as a priority for subsequent testing. Because the user responses and geographic reference records were simulated, these measures do not represent observed farmer usability or independently measured field positional accuracy]]>
