Soo Koobid:

Dabagalka GPS-ka ayaa si isa soo taraysa loogu isticmaalay daraasaadka duurjoogta tobanaankii sano ee la soo dhaafay, laakiin waxqabadkiisa si buuxda looma qiimayn, gaar ahaan kuwa cusub ee gudbiya faylasha fudud. Waxaan qiimeynay waxqabadka siddeed gudbiye oo GPS ah oo lagu sameeyay Shiinaha annagoo ku dhejinayna Crested Ibises Nipponia nippon oo ku kooban laba qafis oo la qabsasho ah oo ku dayanaya deegaanno dhab ah. Waxaan xisaabinay masaafada u dhaxaysa goobaha GPS-ka iyo bartamaha qafisyada inay tahay qaladka meelaynta, waxaanan isticmaalnay khaladaadka meelaynta 95% (boqolkiiba 95) si aan u qeexno saxnaanta. Guusha meelaynta waxay celcelis ahaan ahayd 92.0%, taasoo aad uga sarreysa tii daraasadihii hore. Goobaha si siman looguma qaybin Fasalka Goobta (LC), iyadoo goobaha LC A iyo B ay yihiin 88.7%. Khaladka meelaynta 95% ee la arkay ee goobaha LC A (9-39 m) iyo B (11-41 m) aad ayuu u saxnaa, halka ilaa 6.9-8.8% goobaha tayada liita laga helay LC C iyo D iyadoo > 100 m ama xitaa > 1,000 m qalad meelaynta. Guusha booska iyo saxnaanta way kala duwanaayeen goobaha tijaabada, malaha waxay sabab u tahay farqiga qaab-dhismeedka dhirta. Sidaa darteed, waxaan ku doodeynaa in gudbiyeyaasha la tijaabiyay ay bixin karaan tiro badan oo xog tayo sare leh oo loogu talagalay daraasadaha heerka wanaagsan, iyo tiro goobo tayo liidata oo u baahan fiiro gaar ah. Waxaan soo jeedineynaa in HPOD (barxinta saxda ah ee toosan) ama PDOP (barxinta saxda ah ee booska) la soo sheego halkii laga sheegi lahaa LC si loo cabbiro saxnaanta goobta ee goob kasta si loo hubiyo aqoonsiga iyo shaandhaynta goobaha aan macquulka ahayn.
