【Geog】5** Map Skills分享
map skill 出的題數雖然唔多,但基本上一分都盡量唔好失,要攞晒MC既22%其實係要40條MC全對先得,所以都唔好忽略Map skill。
我個人就好少做坊間啲練習,主要做dse啲map reading,做錯既題記住做多幾次。

Measure area 題
通常本書會叫你畫0.5cmx0.5cm/1cmx1cm 既格仔,但真 正考果陣畫格仔實在好浪費時間,所以有得簡就盡量貼住 要搵那個feature 畫個長方形,再減走多餘的面積
Conventional sign 題
第一要認晒啲signs,特別記住 swamp 同 mangrove 喺 1:20000,1:5000 都唔同。山上面綠色係woodland, 白色係 grassland
Gradient 題
除左要記得gradient 條式,睇水邊既 contour line 要小 心,唔好assume water level of reservoir 都係 0m。計footpath or road 長度記住攞紙條度(eg 度average gradient of road from spot height 60.1 to spot height 4.9,唔 係度連起兩點那條直線),但個人建議攞繩,省掉撕紙時 間
Cross section 題
大致上睇頭睇尾,睇 key,睇山丘
Transect 題
eg transect from 470137 to 470127,就畫條直線穿過 470137 同 470127,之後睇 land use,institutional 係 library, police station, post office, school, etc.
Intervisible 題
總之無突然高出黎既contour line 就 intervisible
Bearing 題
分清compass point(NESW)同 reduced bearing(N/S__° E/W),記住從 from 之後開始睇
