Based on our results, we were ab le to find seven g oodspots with in th e City of Los Ang eles. From th ere, wec h ose two loc ations, th at would b est serve th epopulation. Looking at "m ap2," you c an see th at itc ontains th e six c riteria th at th e planning ag enc y h asasked for. Moreover, b ased on th e b asem apb ac kg round, it displays a flat loc ation c lose to a ruralarea, th at is easily ac c essab le. Lastly it is far awayfrom existing parks g iving th e loc al patrons, a c loseplac e to rec reate.

Results:Th e loc al planning ag enc y h as asked us to find a b est plac eto c reate a new park with in th e City of Los Ang eles. Th ereare spec ific c riteria as to wh ic h values and data are to b ec onsider in pic king th e plac e. Th ere are six c riteria listed, andth ey are over 10 ac res in size, 500 feet away from m ajorfreeway, outside of a wetland, with in “open spac e”, h aving aslope less th an 15%, and far from existing parks. By usingGIS and spatial analysis tec h niques, it c an h elp provide th eessential tools in determ ining th e b est loc ation in b uilding anew park.

Introduction:

We ob tained th e data for th is projec t on th e CS U NGeog raph y Departm ents Y drive. Th e data inc luded severalpolyg on feature c lass files, and one dig ital elevation m odel(DEM).We first isolated th e features we were using from eac h c lass.From th e landuse feature c lass we selec ted areas of openspac e and c reated a new layer c alled “la_opnspc ”. From th eland_type feature c lass we selec ted areas th at fell into th eArts and Rec reation c ateg ory and c reated a new layer c alled“la_parks”. Next we resam pled th e la_dem to h ave a pixelresolution of ten m eters. Before c onverting our vec tor files toraster we erased th e wetland polyg ons from th e newlyc reated open spac e layer so th at we would not inc lude th oseareas in our final selec tion. From th e la_dem we c alc ulatedslope and c reated a new raster file c alled “la_slope”. Afterth at we c onverted th e new la_opnspc and la_parks layer andth e orig inal m jr_rds layer to raster files. We used th eEuc lidian distanc e tool to find distanc es for th e la_parkslayer and la_roads layer. Next we rec lassified th e four newraster layers, la_slope, la_roads, la_parks and la_opnspc .Eac h layer was rec lassified into six c lasses with values 0-5so th at th e final total sc ore th at a g iven area c ould rec eive is20. Th e la_slope layer was b roken down so th at th e flattestareas rec ieved a sc ore of 5 and areas over 15 perc entrec eived a sc ore of 0. Th e la_roads layer was rec lassifiedso th at areas next to m ajor h ig h ways (0-500ft.) rec ieved asc ore of 0 and areas just b eyond 500ft. rec ieve a sc ore of 5sinc e th e ag enc y wanted th e new park ac c essib le for th epub lic . Areas far away from m ajor h ig h ways rec eived asc ore of 1 sinc e th ey were only ac c essib le to a sm all portionof th e population. Th e la_parks layer was rec lassified soth at areas th at are th e furth est from existing parks rec ieved asc ore of 5 and areas touc h ing or neig h b oring existing parksrec eived a sc ore of 0. Th e layer la_opnspc was just g ivenone value (5) sinc e you are eith er in an area of open spac eor you are not. Th ose areas th at fell into an area of openspac e rec eived a sc ore of 5. Finally we used th e rasterc alc ulator to find th e b est areas possib le b ased on th ose fourc riteria. Th e h ig h est sc ore th at a loc ation for a perspec tivepark rec eived was a sc ore of 16. We took all areas th atrec eived a sc ore of 14 or h ig h er and c onverted th ose areasb ac k to polyg ons (vec tor) so we c ould c alc ulate and isolateth e areas th at were g reater th an ten ac res in size. Fromth ere we were ab le to settle on two plac es th at would b e th em ost ideal to b uild a new park in th e City of Los Ang eles.
