topic turning lines into polynomials?? in ArcGIS GeoStatistical Analyst Questions https://community.esri.com/t5/arcgis-geostatistical-analyst-questions/turning-lines-into-polynomials/m-p/204466#M503 <HTML><HEAD></HEAD><BODY><SPAN>Hello</SPAN><BR /><BR /><SPAN>I have a question for the forum.</SPAN><BR /><BR /><SPAN>To make a long story short...I have a view with hundreds of hurricane tracks (lines). Each storm consists of a number of lines segments, each giving the latitude/longitude of the hurricane at a certain time.The length of the line is the distance to the next observation, which is the start point for that line segment . Observations occur every six hours throughout the length of the storm. Each storm has a unique identification number, which can be used to combine all the segments into a single storm. We also converted this into a point file, with a midpoint in the center of each segment. </SPAN><BR /><BR /><SPAN>We want to take these tracks (hurricanes in the Atlantic Ocean) and find a kind of 'average' track type between them. To do so, I assume we need to take this line shapefile (or point shapefile) and convert these into a specific polynomial function for each storm. Then from this long list of polynomial functions, I also assume that we can run a regression on them to find the average track type.</SPAN><BR /><BR /><BR /><SPAN>My question to the forum is - is there a way on ArcMap (maybe using a geostatistical extension/wizard) to change all of these lines (points) into polynomials? Also, how to plot these geographically...i.e. how to translate these polynomials into a lat/long grid system? </SPAN><BR /><BR /><SPAN>Thanks</SPAN></BODY></HTML> Thu, 02 Sep 2010 17:15:34 GMT thomasbianchette 2010-09-02T17:15:34Z turning lines into polynomials?? https://community.esri.com/t5/arcgis-geostatistical-analyst-questions/turning-lines-into-polynomials/m-p/204466#M503 <HTML><HEAD></HEAD><BODY><SPAN>Hello</SPAN><BR /><BR /><SPAN>I have a question for the forum.</SPAN><BR /><BR /><SPAN>To make a long story short...I have a view with hundreds of hurricane tracks (lines).
