15-1. A 100-ft grid is located over an area that measures 800 ft in the north-south direction and 800 ft in the east-west direction. The southwesterly corner is designated A-1 and the southeasterly corner is designated I-1. The northwesterly corner is designated A-9 and the northeasterly corner is designated I-9. Elevations are obtained at the grid points using a total station instrument, rounded off to the nearest foot. These are tabulated as follows: 375 372 366 360 354 350 340 322 302 312 365 364 8 372 372 370 368 362 361 339 7 366 365 365 366. 362 361 347 319 359 328 328 6. 363 353 350 360 362 350 347 361 340 335 343 352 350 338 334 4 360 344 329 328 337 339 325 321 321 3 360 343 320 317 318 318 313 312 312 308 302 303 323 326 2 358 343 316 310 303 291 340 B 1 353 318 310 303 297 292 A C D F G H Plot a grid to a scale of 1 in. = 200 ft and draw in 10-ft contour lines.
