MAPVEC(3NCARG)

✨ MAPVEC ✨ (a.k.a. MAPVEC(3NCARG) from the NCAR GRAPHICS fam 💖)

okay bestie, sit down, hydrate, and let me tell you about the little map-drawing icon that could 🎀

---

🌸 NAME 🌸

MAPVEC — draws lines on a map. that's it, that's the vibe. it's used in conjunction with MAPFST, they're a package deal, you never see one without the other fr fr 💅

---

🦋 SYNOPSIS 🦋

CALL MAPVEC (RLAT,RLON)

---

✨ C-BINDING SYNOPSIS ✨

#include <ncarg/ncargC.h>

void c_mapvec (float rlat, float rlon)

---

💜 DESCRIPTION 💜

• RLAT and RLON — these are input expressions, type REAL, and they say where the "pen" should get moved to. both are in degrees. 🖊️✨
  • RLAT has to be between -90. and +90., inclusive. no cap, those are the walls.
  • RLON has to be between -540. and +540., inclusive. yes, that's a whole extra lap and a half of longitude, they really said "go around as many times as you want bestie" 😭

---

🌈 C-BINDING DESCRIPTION 🌈

the C-binding argument descriptions are literally the same as the FORTRAN argument descriptions. same energy, different language, we love a bilingual king 👑

---

🎀 USAGE 🎀

so here's the tea ☕ — this statement:

CALL MAPVEC (RLAT, RLON)

is equivalent to:

CALL MAPIT (RLAT, RLON, 1)

it moves the "pen" (and the pen is in the "down" position, so it's actually drawing, not just hovering) to the next point in a series of points. so like, it's the connective-tissue function, it's the "and then" of your map line 💫

go read the man page for MAPIT if you want the full lore, bestie, it's all there 🫶

---

🔥 ACCESS 🔥

to use MAPVEC or c_mapvec, you gotta load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c — preferably in that exact order. the order matters, don't be chaotic 🙈
