Ubwoko (Inyoni):Ibis ya Crested (Nipponia nippon)

Incamake:

Gukurikirana GPS byagiye bikoreshwa cyane mu bushakashatsi ku nyamaswa mu myaka yashize, ariko imikorere yayo ntabwo irasuzumwa neza, cyane cyane ku byuma bishya byohereza ibintu byoroheje. Twasuzumye imikorere y'ibikoresho umunani byohereza ibintu bya GPS byakorewe mu Bushinwa tubihuza na Crested Ibises Nipponia nippon bifungiye mu byumba bibiri byo kwimenyereza ibidukikije bisa n'aho batuye nyabyo. Twabaruye intera iri hagati y'aho GPS iherereye n'umurongo wa centroid w'ibyumba nk'ikosa ryo gushyiramo ibintu, kandi dukoresha amakosa ya 95% (95th percentile) yo gushyiramo ibintu kugira ngo tumenye neza. Intsinzi yo gushyiramo ibintu yari impuzandengo ya 92.0%, ari hejuru cyane ugereranyije n'inyigo zabanje. Aho hantu ntabwo hakwirakwijwe kimwe na Location Class (LC), aho LC A na B zari 88.7%. Ikosa ryagaragaye rya 95% ryo gushyiramo ibintu mu bice bya LC A (9-39 m) na B (11-41 m) ryari ryiza cyane, mu gihe kugeza kuri 6.9-8.8% by'ahantu hatari heza byagaragaye muri LC C na D hamwe n'ikosa ryo gushyiramo ibintu kuri metero > 100 cyangwa ndetse na metero > 1,000. Intsinzi mu gushyira ahantu hageragerejwe n'ukuri byari bitandukanye hagati y'ahantu hageragerejwe, birashoboka ko byatewe n'itandukaniro ry'imiterere y'ibimera. Bityo, tuvuga ko imashini zageragerejwe zishobora gutanga umubare munini w'amakuru meza yo gukora ubushakashatsi burambuye, hamwe n'ahantu hatari heza hakenewe kwitabwaho. Turasaba ko HPOD (horizontal dilution of precision) cyangwa PDOP (positional dilution of precision) byatangazwa aho gutanga raporo ya LC nk'igipimo cy'ukuri kw'aho hantu kuri buri hantu kugira ngo hamenyekane kandi hasukurwe ahantu hadashoboka.
